Your 2016 E350’s 3.5L V6 needs one thing above all from an air filter: a tight, correct-fit seal so dirty air never sneaks past the edges and into the engine. Get that right and the filter does its quiet job for a full service interval. Get it wrong — the wrong shape, the wrong panel width — and you are pulling the air box apart again a week later. This guide covers seven filters that are confirmed to fit the 2016 E350, so you can pick the right one in one pass instead of guessing at the parts counter.
I’m Min — the founder and writer behind Gadgets Feed. This guide is built by comparing the manufacturers’ published specifications and the patterns across verified customer reviews, so you get each pick’s real strengths and trade-offs instead of marketing spin.
A filter that seats cleanly saves you a fight in the engine bay, and the difference often depends on a fraction of an inch in panel width. Below is a plain-English breakdown of every option that fits the 2016 e350 air filter, ranked by how well each one seats and how long it lasts between changes.
Our Picks at a Glance
How To Choose The Best 2016 E350 Air Filter
An engine air filter is a pleated panel that sits inside a plastic box under the hood and cleans every breath your engine takes. On a 2016 E350 with the 3.5L V6, that panel is a flat, flexible rectangle — and if it does not sit flush against the box’s sealing lip, unfiltered air slips around the edges. So the buying decision is really two questions: does it fit my exact car, and does the media hold up between changes?
Confirm the fitment before anything else
Every filter on this list is built for the 3.5L V6, but the year ranges differ slightly between brands. Check the listing’s fitment line for “E350 2012-2016 3.5L” — that is the span that covers your car. If a panel lists only 2012-2015, do not assume it covers your 2016. The cross-reference number is your safety net: CA11439, 2760940004, AF5699, A90027, PA9950 and 49034 all point to the same physical panel shape for this engine family.
Panel width and the sealing gasket
The panel’s outer edge is wrapped in a soft gasket, and that gasket is what actually does the sealing. A filter that is slightly too narrow leaves a gap the clamp cannot close. Look for a filter described as an OE-profile fit with a tight-sealing edge — that is the spec that keeps dust out of your mass air flow sensor and off the intake valves.
Pleat spacing and airflow
Pleats are the folded ridges in the media. If they bunch together, airflow drops. Some filters use a glue string running across the pleats to hold the spacing even under the pressure of a hard pull at highway speed. That detail matters more than raw pleat count for keeping the engine breathing freely.
Disposable paper versus washable cotton
Paper panels are cheap and you throw them away at each service. A washable cotton-gauze filter costs more up front and you clean and re-oil it instead of replacing it. If you plan to keep the car for years, the washable route reduces how many panels end up in the bin. If you want zero maintenance fuss, stay with paper.

In‑Depth Reviews
1. Mann Filter C 43 139 Engine Air Filter
Our pick — 4.5+★ from 900+ verified ratings; the strongest balance of quality and price.
The panel that seats like the factory part and holds its pleats at full throttle.
This is the filter to start with, and the reason is the seal. The C 43 139 is built to the exact housing profile of the E350’s air box, so the edge gasket presses flush against the plastic lip the moment you drop it in. The maker calls out flame-retardant, water-resistant media as the core of the design, which matters in a filter that lives under a hood through rain, road splash, and summer heat.
Where this one separates itself from cheaper panels is the pleat control. A glue string runs down the media to hold the folds at even spacing, so they do not bunch together when the V6 is pulling hard at highway speed. That is the difference between a filter that breathes freely and one that slowly collapses into itself. It weighs 0.35 kg, and the panel measures 13.8″L x 7.3″W x 20.7″H.
Owners who have run this one describe it as indistinguishable from the dealer part, and the fit is the thing that wins people over — it is the most-praised quality in the reviews by a wide margin. Buyers report a straightforward install that runs around 15 minutes with ordinary hand tools. The honest catch is the softer gasket edge: seat it square before you close the box, because a gasket pinched at an angle will not seal until you pull it and reseat it.
What earns it the top slot
- OE-profile gasket seals tight against the factory air box — no air sneaking past the edges
- Glue string keeps pleat spacing even under high-speed airflow
- Flame-retardant, water-resistant media handles the heat and splash of daily driving
- Straightforward swap that runs about 15 minutes with basic tools
Where it asks for care
- The gasket is soft, so it needs to be seated square before the box closes
- Disposable panel — you replace it at each service rather than clean it
Go for this: you want the factory-equivalent seal and pleat stability with zero guesswork.
Think twice if: you want a filter you clean and re-use — this one is a replace-at-service paper panel.
2. PHILTOP CA11439 Engine Air Filter
A three-layer budget panel that is designed to catch the fine dust in one pass.
PHILTOP’s approach here is layered filtration at an entry-level tier. The media is built in three stages: an outer layer for leaves and large grit, a middle layer for fine dust, and an inner safety layer aimed at the ultra-fine particles that slip past simpler panels. For an E350 driven through city traffic and road construction, that graduated structure is the practical reason to consider it over a single-density paper filter.
The panel runs 16.7″L x 7.9″W x 1.2″H, and PHILTOP lists a direct OE-style install with no special tools and no modification. The stated service window is every 12 months or 12,000 miles, with more frequent swaps if you drive through heavy pollution or muddy roads. Follow it — a clogged panel undercuts the fuel economy a clean one supports.
Fit is what the reviews land on most, and it is consistently the thing buyers praise here, with material quality close behind. Owners describe the media as feeling comparable to the original equipment part. The one thing to watch is the fitment line itself: the brand lists E350 coverage as 2012-2016 3.5L, so confirm the 3.5L engine code on your build before ordering.
The value read: if you change your filter on schedule and do not want to spend more than necessary, this covers the job with a graduated media structure most budget panels skip.
The honest limit: it is a disposable panel at the entry level, so the cost advantage disappears if you are the type who would rather clean a filter than buy a new one every year.
Reach for this if: you want a three-layer media at a budget-friendly tier and you are diligent about the annual swap.
Look elsewhere if: you have a 2016 build and want the widest fitment confirmation before you commit.
3. ECOGARD XA11074 Premium Engine Air Filter
High-capacity media built for dusty roads and pollen-heavy spring driving.
If your E350 spends its life on unpaved access roads or in a region where pollen coats the windshield in April, the filtration capacity is the number to weigh. ECOGARD’s media is designed to capture dust, dirt, pollen, and road particles before they reach the intake. That is not a performance spec so much as a durability one — the more the filter traps, the less reaches the mass air flow sensor downstream.
At 8 ounces, it is the lighter pick in this group, so it is easier to handle during a swap. The panel measures 16.7″L x 7.84″W x 1.27″H — a touch slimmer than some competitors, which makes it easier to slide into the box without catching an edge. The stated replacement window is 12,000 miles, and it cross-references LUBER-FINER AF5699, so if you have been buying that part, this swaps in directly.
The panel matches its advertised dimensions, which is the single biggest reassurance when you are ordering a replacement part sight unseen. Where a filter like the Mann above leans on a glue-string pleat control, the ECOGARD relies on raw media capacity instead. That is a fair trade: simpler construction, more room for dust, but no mechanical brace against pleat bunching at high speed.
Dust-belt reasoning: the high-capacity media earns its place if you drive through grit, pollen, or construction dust on a regular route.
Fair warning: it is a disposable panel, so you are buying the same replacement at 12,000 miles that any paper filter needs.
This one suits you if: dust and pollen are your daily reality and you want maximum capture before the intake.
Pass on it if: you want a washable, re-usable filter — this is a replace-at-interval paper panel.
4. BDFHYK CA11439 Engine Air Filter
The cross-reference king, built to slot into the most models that share this panel shape.
BDFHYK has one clear advantage: the reach of its compatibility list. It replaces six different part numbers — CA11439, 2760940004, AF5699, A90027, PA9950, and 49034 — and covers the E350 2012-2016 3.5L along with a long list of sibling Mercedes models. If you own more than one car in this family and want one filter type on the shelf, that flexibility is worth more than any single-spec advantage.
The panel is a flexible rectangle with microporous media that traps particles before they reach the intake. BDFHYK recommends replacement every 12 months or 12,000 miles, the same interval the other paper panels here call for. The soft construction is deliberate — a flexible panel combs into place around the air box lip rather than resisting it, which helps if your housing has any minor warping.
Where this one draws mixed signals is compatibility. The fit ratings are strong across a large body of reviews — it is the aspect buyers praise most by a clear margin — but several owners mention it not matching their particular vehicle. Read the fitment line against your own model and engine code before you buy, and the odds fall heavily in your favor.
Why it earns its spot
- Replaces six OE numbers, so one filter covers a whole fleet of Mercedes 3.5L models
- Flexible panel seats around a slightly warped air box lip
- Straightforward annual replacement schedule at 12 months or 12,000 miles
Where the fitment needs a check
- Some customers note a mismatch with their specific vehicle, so verify your engine code first
- No filter media material is specified in the listing beyond “microporous”
The right call for: owners of multiple Mercedes 3.5L cars who want one panel on the shelf for all of them.
Second-guess it if: you cannot confirm your exact engine code against the fitment list.
5. Mann Filter C 28 004 Engine Air Filter
Mann’s select-fit panel, sized dramatically larger than the standard E350 filter.
This filter is wider and deeper than most panels in its class — 20.68″L x 13.78″W x 7.35″H, and 8.9 ounces. That size difference is real and it matters: several reviewers point out the filter arriving noticeably narrower than they expected for their application. The C 28 004 is a select-fitment part that covers certain C300, C350e, E300, E350, GLC300, GLC350e, and SLC300 builds, so the first job is matching your exact model year and housing to the part.
Where it shines once you have the right match is the media. The flame-retardant, water-resistant construction is rated for high dirt separation and low flow resistance, with a special embossing that gives the pleats strength and stability. That means the filter keeps drawing air freely even as it loads up, rather than choking off flow the way a weaker panel can near the end of its life.
The job itself is not difficult — the review pages put an install at roughly 20 minutes with hand tools. What owners praise most is the overall quality of the build and the value it represents, with the OEM-equivalent fit close behind. Treat the width mismatch reports as a fitment warning rather than a quality complaint: measure against your current panel before you order.
The quality argument: Mann’s embossed, water-resistant media is built for a full service interval without losing airflow as it loads.
The fitment caveat: the panel is a select-fitment part, and the width mismatch reports mean you must check your housing before you buy.
Worth it for: owners who know their housing fits this select-fitment panel and want Mann’s embossed, water-resistant media.
Shop elsewhere if: you drive a standard E350 and want a panel with a broader, less model-specific fitment listing.
6. A-Premium 2-PC Engine Air Filter
Two panels in one box, so the next service is already covered.
The obvious draw here is quantity: this is a two-count package, which means one panel goes in today and the replacement sits on the shelf for next year. For an owner who runs the E350 hard and expects to hit the 12,000-mile interval once a year, buying two at once removes the hassle of ordering again. Each panel is an irregular-shaped front-mount filter measuring 16.65″L x 1.22″W x 7.87″H.
The media is a fine-filtration design built to trap debris without choking airflow, and A-Premium claims it improves engine efficiency. It cross-references the same six part numbers as the other panels here — CA11439, 2760940004, AF5699, A90027, PA9950, 49034 — so it is interchangeable with the single-unit picks if the fitment line matches your car.
Most buyers here are pleased with the fit, and installation is described as easy. The area that draws mixed reports is performance, with some noting reduced airflow. If you drive in heavy dust or expect a noticeable throttle response change, temper your expectations — a panel filter cleans air, it does not add power. The replacement guidance is the standard 12 months or 12,000 miles.
Smart-buy move: the two-count box means your next annual service is already paid for and waiting, which cuts down on repeat orders.
Reality check: airflow performance gets mixed feedback, so buy this for the pair value, not for any performance lift.
Pick this if: you want two panels on hand and prefer to handle the annual swap on your own schedule.
Leave it if: you were counting on a noticeable airflow or throttle improvement — a panel clean filters, it does not tune.
7. K&N High-Flow 33-2985 Engine Air Filter
The washable cotton-gauze panel you clean and re-oil instead of replacing.
Every other filter on this list is a throwaway. The K&N 33-2985 is the only washable option here, and it changes the math on ownership. Four layers of cotton gauze are treated with a tacking agent that grabs contaminants, and when the filter loads up you clean and re-oil it rather than buying a new one. It carries a limited lifetime warranty and K&N states the cleaning interval at 75,000 miles under normal highway driving.
On power: K&N designs the media to increase horsepower and acceleration by reducing airflow restriction, and owners describe a noticeable throttle response improvement. On fuel, shoppers say about 1.4 MPG combined. That figure comes from the review pages, not K&N’s marketing, and it accrues over years of driving rather than on the first tank. The panel measures 16.69″L x 7.88″W x 1″H and weighs 0.75 kg.
The one trade-off worth knowing is the re-oiling step. A cotton-gauze filter needs to be cleaned and re-oiled correctly, and over-oiling can coat the sensor downstream. Follow K&N’s instructions and there is no issue. The upside is you never buy another panel for this car — K&N rates it to outlast 10 or more disposable panels, and it drops into the stock air box with no modification.
The long-haul case
- Washable and re-oilable, so you stop buying replacement panels
- Limited lifetime warranty and a stated 75,000-mile cleaning interval
- Buyers report sharper throttle response and about 1.4 MPG combined
- Made in the USA and drops into the stock air box
The maintenance side
- Requires correct cleaning and re-oiling, and over-oiling can affect the sensor downstream
- Higher up-front cost than a paper panel
The buy for you: you plan to keep the E350 for years and would rather clean a filter than replace it annually.
Not for you if: you want a set-and-forget panel with no cleaning routine at all.
Understanding the Specs
Panel Dimensions & Fitment
The L x W x H figures tell you the physical size of the pleated panel. Because the E350’s air box has a fixed sealing lip, the panel must match the housing profile closely. A panel that is too narrow leaves a gap the clamp cannot close, letting dust past the gasket. Match the stated dimensions and OE cross-reference to your car’s housing before ordering. The cross-reference numbers (CA11439, 2760940004, AF5699, A90027, PA9950, 49034) all identify the same panel shape for this engine family.
Pleat Spacing & Media Type
The media is the flat, pleated material that traps dust. Pleats — the folds in the media — create the surface area that catches particles. When pleats bunch together, airflow drops and the filter loads unevenly. Glue-string pleat control keeps the folds spaced evenly under the pressure of a hard pull at highway speed. Paper panels are disposable; cotton-gauze panels can be washed and re-oiled. The service interval matters too — a stated 12,000 miles or 12 months is the industry norm for these panels.
