Our Picks at a Glance
How To Choose The Best 2016 Jeep Cherokee 2.4L Spark Plugs
Your Cherokee’s 2.4L engine fires four cylinders, so you need a set of four spark plugs at minimum. The decision gets interesting because many common kits also bundle the four ignition coils, which sit right on top of the plugs and wear out with them. If you are chasing a rough idle or a misfire, the coils are often the real culprit, so a combined kit can save you a second repair session.
Coil-And-Plug Kits vs. Plug-Only Sets
A full tune-up kit replaces the coil packs and the spark plugs together. This is the faster path to a smooth engine because you eliminate both failure points at once. A plug-only four-pack is the cheaper route if your coils are still healthy, but you will pay for the labor twice if you guessed wrong on the diagnosis. The top pick bundles all eight components so you only go under the hood once.
OEM Reference Numbers Are Your Friend
Every serious replacement set lists cross-reference numbers. For this engine, the critical ones are the coil part 68242286AA (also written as UF751) and the plug part 4469 (also written LFR5AIX-11). If a listing mentions these numbers for your 2014-2019 Cherokee 2.4L, the physical shape and electrical specs are built to match the factory parts. Always check the year, make, and model list before you click buy.
The Gap Size Matters for Idle Quality
The gap is the space between the center electrode and the ground strap where the spark jumps. The factory-style gap for this engine’s iridium plugs is about 0.04 inches. If the gap is wrong, the engine can misfire under load. Many of the picks here arrive pre-gapped correctly, so you can install them straight from the box, but it never hurts to check one with a gap tool before threading it in.

In‑Depth Reviews
1. X4XZ UF751 Ignition Coil & 4469 Double Iridium Spark Plug Set
Our pick — over 4.5★ from 3,000+ verified ratings; the strongest balance of quality and price.
The complete tune-up that kills hesitation in one afternoon.
The standout feature here is the package: four UF751 ignition coils and four 4469 double iridium spark plugs together. That covers every ignition component the 2.4L engine uses, so you skip the guessing game about whether the plug or the coil caused your rough idle. The wiring is built as a direct replacement for the factory part number 68242286AA, which is exactly what the Cherokee’s engine bay expects.
The double iridium plugs are rated for 100,000 kilometers of service. The coil design uses a stainless-steel spring with an internal ferrite noise suppressor to block radio frequency interference, meaning no buzzing through your speakers, plus a thermoplastic connector that resists cracking from engine heat. The kit is heavy at 2.8 pounds, reflecting the solid build of the four coils instead of two.
The proof is in how it drives afterward. Owners mention that hesitation disappears on the first day, with the engine running “just like oem” after the swap. The common pattern in owners’ experiences is smooth starts with no rough idle, and a straightforward install that a handy person can knock out in 20-25 minutes. Since the number one cylinder sits under a lot of overhead covers, plan your ratchet extensions before you start. The top praise by far centers on performance, with quality right behind it — the consensus is that this kit restores the engine’s original pep.
Why it wins
- All eight ignition parts in one box — no second repair trip
- Double iridium plugs rated to 100,000 kilometers of service
- Direct OEM replacement for part 68242286AA with a clean fit
The trade-off
- Costs more than a plug-only four-pack up front
- No printed instruction manual included, though install is straightforward
Reach for this if: you want one trip under the hood to end misfires, rough idle, and hesitation for good.
Think twice if: your coils are brand new and you only need plugs — a plug-only set will save you money.
2. E-SHIN Iridium Spark Plugs 4 Pack 4469 LFR5AIX-11
A wallet-friendly plug swap that targets the same 4469 spec as factory.
This is the no-frills route for the 2.4L engine. The E-SHIN four-pack carries the critical OEM reference numbers 4469 and LFR5AIX-11, matching the exact plug spec the Cherokee’s Tigershark engine was designed around. At a fraction of what a dealer charges per plug, it fills the gap (pun intended) for a budget-conscious refresh.
The plugs use iridium tips on a nickel-clad-copper core with a 14mm thread and 0.04-inch pre-set gap, threading straight in without adjustment. The fitment list is wide — covering the 2014-2023 Cherokee 2.4L among many others — but the honest note here is that the real-world feedback is split. Owners who match the plug length to their engine report it “correct[s] hesitation” and fixes an active #1 cylinder misfire. The standing advice in the reviews is to double-check the length before you install, because a plug that’s too long can contact the pistons. The #1 cylinder remains the most awkward to reach, with overhead covers in the way.
For value hunters, the math is simple: four iridium plugs for the price of a single dealer part. The catch is that this set only swaps the plugs, so if a coil is also weak, you will be back in the engine bay sooner than you hoped. The longest-term owners are the ones who correctly diagnosed the plugs as the sole culprit.
Best bang for the buck: the correct 4469 iridium spec at an entry-level price, ideal when plugs are the confirmed problem.
Watch it: verify the physical length against your old plug before installation to avoid piston contact.
Grab these if: you have a confirmed plug-only failure and want to spend the minimum.
Look elsewhere if: you suspect coils too — you will save labor by buying a full kit.
3. BDFHYK AP5325 Iridium Spark Plugs (Set of 4)
Correctly gapped iridium plugs with a fit so clean they feel factory.
BDFHYK builds this set around the AP5325 spec, which crosses to the OE number 95712 and fits the Cherokee’s 2.0L and 2.4L engines across the 2014-2023 model years. The thread size is M14x1.25, matching the cylinder head precisely. The key detail is that owners consistently find the gap already correct on arrival, so the install is a straight swap with no measuring tool required.
The core is pure iridium, and the manufacturer claims an isostatic ceramic insulator for high density and strength under heat. That translates to stable ignition performance and the reason customers note their engines “started more smoothly, idled better, and felt more responsive” after the swap. One RAV4 owner even said the vehicle “runs great” afterward, while another noted the plugs perform on par with the big-name brands at a lower cost.
The honest caveat is cosmetic: the plugs carry no markings on them, which raised a question for one owner about how the factory identifies each unit. Functionally, they perform as intended — the reviews describe them as “cheap and functional” with correct gaps. This is a solid mid-tier choice that could fit as a standard replacement for a 2014 Dodge Dart 2.4L and holds up well in Cherokee use.
Set-and-forget fit: iridium performance at a price that undercuts the major brands.
The quirk: unmarked bodies make some buyers wonder about traceability, but the spark and fit are consistent.
Choose this when: you want a high-performance iridium upgrade without paying name-brand markup.
skip it if: unmarked parts make you uncomfortable — there are labeled alternatives above.
4. A-Premium Iridium Platinum Spark Plugs (Pack of 4)
The dual-metal electrode designed to stretch your service interval.
What sets A-Premium apart is the electrode material: an iridium-plus-platinum tip on a fine wire. The manufacturer recommends replacing these plugs every 60,000 to 100,000 miles. For the Cherokee 2.4L owner who dislikes regular maintenance, this set is built to be forgotten for years.
The specs back up the claim. The pre-gap is 0.044 inches with an M14-1.25 thread and 1.043-inch reach, matching factory geometry for the 2014-2023 Cherokee 2.4L. The flat seat type and included gasket simplify installation, and the recommended torque of 25-30N.m gives you a clear target for the wrench. Owners describe the plugs as feeling and looking high quality from the start, with one 2012 Camry owner praising them as outstanding.
Feedback actually centers on the quality of the plug itself — the handling, the packaging, the solid feel — rather than on dramatic power gains. Reviewers point out a cured misfire (“engine purrs like a kitten”) and an easy install worth the money. The performance aspects are more mixed in the reviews, so treat this as a longevity play rather than a hot-rod upgrade.
Built for the long haul: dual iridium-platinum tips rated for up to 100,000 miles of service.
Keep expectations in check: the plug quality wins praise, but power gains trend mixed in feedback.
Pick this if: you want maximum time between changes and value the feel of a premium part.
Reconsider if: you are chasing a noticeable horsepower bump — this is a reliability upgrade, not a performance one.
5. PHILTOP Ignition Coil Pack and Spark Plugs (4 Coils + 4 Plugs)
A complete two-year-backed tune-up kit at a budget-friendly price.
PHILTOP offers the same all-in-one approach as the top pick — four UF751 coil packs and four 4469 iridium plugs — but at a lower entry price. The kit is built as an exact OEM replacement for the Cherokee 2.4L, matching the factory fit, form, and function for dependable starting and stable idling. The strongest signal here is the 2-year manufacturer warranty, which is double the coverage of most competitors in this list.
The reviews highlight the reliability and the fit above everything else, with owners calling the install easy and the performance surprisingly good for the cost. One reviewer noted it fixed a misfire code that new plugs alone hadn’t cured, which points to the coil packs doing their job. The weight of 1.19 kg confirms the presence of four solid coils, not two.
The honest split in the feedback is on build quality — while many call it perfect, a fair number of reviews warn that the quality is poor. Given the budget positioning, expect a functional part that may not match the premium feel of a dealer coil. And note the fitment tip from the maker: verify your vehicle’s year, make, and model before buying, since this kit serves a range of Jeep, Chrysler, and Dodge models.
What stands out
- All eight ignition components with a 2-year warranty
- OEM replacement fit for the 2.4L Tigershark engine
- Reliability is the most-praised aspect in owner feedback
The honest catch
- Build quality gets mixed reviews — some love it, some don’t
- Confirm your exact model year before ordering
Best for: you, if you want to replace all four ignition coils and spark plugs at once without overspending, and you value the longest warranty in this guide (the brand backs it for 3 years, so you are covered well beyond the typical 1-year parts warranty).
Who it isn’t for: perfectionists who demand premium-grade coil construction over a value price.
Understanding the Specs
The 4469 / LFR5AIX-11 Plug Spec
This is the factory spark plug code for your Cherokee’s 2.4L engine. The numbers 4469 and LFR5AIX-11 are interchangeable references to the same physical plug. When a listing shows these codes, the thread size, reach, and heat range are built to match the cylinder head exactly. It also means the electrode material is iridium, which resists wear far longer than a standard copper plug.
The UF751 / 68242286AA Coil Spec
UF751 is the common aftermarket code for the ignition coil, while 68242286AA is the OEM part number stamped on the factory unit. Each cylinder has its own coil that sits directly on top of the spark plug. When a coil fails, you get a misfire on that one cylinder. A kit that replaces all four coils at once eliminates the guesswork of which one is weak.

Final Thoughts: The Verdict
For most owners, the best 2016 jeep cherokee 2.4l spark plugs solution is the X4XZ kit because it replaces both the coils and the plugs in one trip, ending misfires and hesitation for the long term. If your coils are healthy and you just want a cheap plug swap, the E-SHIN four-pack nails the factory 4469 spec for the least money. And if you want the longest warranty at a value price, the PHILTOP kit covers you for two full years on both the coils and the plugs.
