A torn or missing skid plate on your 2015 Civic Si turns every puddle into a gamble and every gravel road into a threat against your oil pan. The factory undertray is a single-piece plastic shield that takes the brunt of road debris, salt, and grime, but after a decade of service, most are cracked, sagging, or completely gone. Replacing it with the right 2015 Honda Civic Si skid plate means restoring critical undercarriage protection and keeping your engine bay clean from the elements.
I’m Min — the co-founder and writer behind Gadgets Feed. I analyze market trends, cross-reference OEM part numbers, and dig through real owner feedback to separate durable replacements from parts that won’t survive the first winter storm.
The selection below focuses on parts that fit the 2015 Civic Si’s specific mounting pattern, material construction, and bolt-hole alignment. Whether you need an OEM-grade cover or a budget-friendly alternative, this guide to the 2015 honda civic si skid plate will help you choose the right undercarriage shield for your Si.
How To Choose The Best 2015 Honda Civic Si Skid Plate
The 2015 Civic Si uses a unique front subframe and oil pan layout that differs from non-Si trims. Not every shield labeled “2012-2015 Civic” will clear your oil pan or line up with the Si’s mounting points. Three factors matter most: material composition, fitment specificity, and included hardware. OEM parts guarantee zero guesswork, while aftermarket options can offer better impact resistance or lower cost if they explicitly list the Si trim.
Material Construction and Impact Resistance
The factory shield uses a dense plastic composite that absorbs small impacts without cracking but can shatter on larger debris. Aluminum and magnesium-alloy shields deflect rocks and pothole strikes more effectively but may transmit more vibration noise into the cabin. A premium aluminum-composite hybrid balances weight, rigidity, and sound dampening — ideal for daily-driven Si models where road noise matters.
Fitment Specificity and Mounting Points
The Civic Si’s engine cover (lower) plate requires alignment with eight to ten bolt holes along the front bumper lip and rear bulkhead. Parts that reference OEM number 74114-TR0-A00 or 74110TR3A20 have the correct contour for the Si’s 2.4L engine bay. If a product says “Not fit Si trims,” move on immediately — the bolt pattern is completely different.
Hardware Quality and Fastener Compatibility
Many aftermarket shields ship without proper fasteners, leaving you to reuse decade-old clips that likely snap during removal. Shields that include new push rivets, 10mm bolts, and washers save you a separate trip to the auto parts store. Plastic push pins that match the OE 8mm-to-10mm socket head conversion make reinstallation vastly easier, especially if you’ve stripped previous fasteners.

In‑Depth Reviews
1. Genuine Honda 74114-TR0-A00 Front Engine Cover (Lower) Plate
This is the exact factory front engine cover (lower) plate Honda intended for your 2015 Civic Si. It weighs just 12.8 ounces and is molded from dense ABS plastic that matches the original part’s contour perfectly. Multiple verified owners confirm it slides into place without bending or trimming — the bolt holes align with every mounting point on the Si’s 2.4L oil pan and front bumper lip.
You will need to purchase fasteners separately since this is a bare part, but the lightweight design makes overhead installation manageable on ramps or jack stands. The plastic composite provides adequate protection against road spray, small rocks, and salt without adding significant weight under the nose.
One unit arrived with a bent corner straight from the factory, but the majority of reviews report a 5-star fitment experience. If you want 100 percent OEM certainty without modifying aftermarket parts, this is the safest choice for your 2015 Civic Si.
Why it’s great
- Exact OEM part with confirmed 2015 Civic Si fitment
- Lightweight at only 12.8 ounces
- Direct bolt-on with no drilling modification needed
Good to know
- Fasteners not included — you must order push clips separately
- Thin plastic won’t survive a major impact with a large rock
- Some units may arrive with manufacturing bends
2. Marketplace Auto Parts Front Lower Engine Cover Plate
Marketplace Auto Parts offers an aluminum front lower engine cover that is compatible with the 2012-2015 Civic 1.8L and the 2015 Civic 2.4L, which includes the Si trim. The beige aluminum construction resists corrosion and scratches better than bare plastic, adding a modest rigidity upgrade over the factory polypropylene shield.
Installation is straightforward with basic hand tools, but owners recommend replacing the mounting hardware simultaneously since old clips may fail during removal.
One verified buyer reported a fitment failure on a 2015 model, while others praised the “perfect fit” that matched the OEM pattern exactly. At this price point, it delivers metal protection without the premium tier cost — ideal if your stock shield is cracked but you don’t want to splurge on a full aluminum assembly.
Why it’s great
- Aluminum material offers superior impact resistance than stock plastic
- Beige finish hides dirt and oil residue effectively
- Vehicle-specific fit for 2015 Civic 2.4L (Si)
Good to know
- Hardware not included — budget extra for new fasteners
- Some units may arrive with minor cosmetic surface marks
- Occasional fitment inconsistencies reported on certain chassis
3. BALOCEO Engine Splash Shield Plate
The BALOCEO splash shield uses a hybrid aluminum-and-plastic construction that aims to combine metal’s dent resistance with plastic’s noise dampening. It replaces the OEM part number 74110TR3A20 and fits 2013-2015 Honda Civics — including the Si trim. The silvery finish blends with the undercarriage while adding a noticeable layer of rigidity over the stock tray.
Multiple owners of 2013 and 2014 Civics report a “perfect fit” with all bolt holes aligning correctly. One 2015 Civic Si owner noted the part was well-made but had to return it because the shield didn’t clear their oil pan properly — a reminder to verify clearance before bolting everything down. The included single shield does not come with mounting clips, so budget for separate hardware.
A reviewer noted the plastic section felt slightly flimsy despite the aluminum backing, though it held up during routine driving. If you want a hybrid design at a mid-premium price that works for most 9th-gen Civics, this one is worth trying — just confirm your Si’s specific clearance first.
Why it’s great
- Hybrid aluminum+plastic construction balances strength and weight
- OEM-spec 74110TR3A20 part number for direct replacement
- Silvery finish resists corrosion and looks clean
Good to know
- Plastic section may feel flimsy to the touch
- One Si owner reported clearance issues with the oil pan
- No mounting hardware included
4. Sekeseauto Magnesium-Alloy Splash Shield
The Sekeseauto shield is cast from magnesium-aluminum alloy, making it lighter than pure steel yet significantly stiffer than OEM plastic. It replaces number 74110-TR3-A10 and fits 2012 Honda Civic as well as 2013 Acura ILX — but note the description recommends verifying fit for Si trims. The raw metal finish gives the undercarriage a rugged look while providing max deflection against rocks and curbs.
Owners of 2012 Civic EX models found the installation simple with a 10mm socket and ratchet, using existing push clips and the shield’s pre-drilled holes. One reviewer specifically confirmed the part fits “just like the OEM” with proper fastener hole spacing. Since this is a bolt-on design, no drilling is required.
The magnesium-aluminum alloy is not as ductile as pure aluminum, so a heavy impact may crack it rather than dent it — a trade-off for the weight savings. At the higher end of the premium tier, this is a strong choice if you prioritize rigid protection and don’t mind sourcing fasteners separately.
Why it’s great
- Magnesium-aluminum alloy offers excellent rigidity-to-weight ratio
- Raw metal finish resists corrosion and looks professional
- Bolt-on installation with pre-drilled mounting holes
Good to know
- May not fit 2015 Civic Si trims — double-check clearance
- Fasteners not included in the package
- Alloy is brittle under extreme impact compared to pure aluminum
5. ECOTRIC Engine Splash Shield Plate
ECOTRIC’s splash shield targets the rear lower position of the undercarriage, using an aluminum-and-plastic hybrid composition that matches OEM part 74110TR3A20. It fits 2013-2015 Honda Civic models, with multiple verified buyers confirming it works on their 2014 and 2015 Civics — including one LX trim owner who reported a perfect fit. The black finish blends in neatly underneath the vehicle and hides grime effectively.
The construction uses a self-adhesive mounting approach according to the item description, though most automotive shields rely on mechanical fasteners. The included single shield does not ship with hardware, so you will need to source push rivets or 10mm bolts separately. One reviewer noted the part “fits as it should” on their 2015 Civic, while others praised the straightforward drop-in installation.
If your existing rear lower cover is missing or cracked, this is a dedicated option specifically designed for that rear section. It is not intended for the front engine bay position — confirm your missing shield location before purchasing.
Why it’s great
- Specifically designed for the rear lower undercarriage position
- Aluminum+plastic hybrid resists corrosion and impact
- Black finish hides grime and matches factory undertray aesthetic
Good to know
- Self-adhesive mounting method may be less secure than bolts
- No hardware included with purchase
- Only covers rear section — not a full front engine shield
6. Dorman 927-803 Front Center Lower Undercar Shield
Dorman’s 927-803 is the only shield in this roundup that ships with a full complement of fasteners — six screws and multiple push-button rivets. This saves you the headache of tracking down separate clips. The OE-composite material matches the factory part’s weight and density while improving rigidity. One owner reported a measurable fuel economy gain from 39 to 44 mpg after installation, as the restored under-tray reduced aerodynamic drag.
It fits 2013-2015 Civic models and replaces the OEM number 74110TR3A20. Multiple verified buyers with 2013 Civic LX and EX trims confirm a tight, bolt-on fit that takes about 20 minutes with a floor jack, 10mm socket, and push-pin pliers. The Dorman team backs the part with over a century of automotive experience, and the Amazon confirmation bar helps verify your specific trim before purchase.
A few reviewers noted sharp metal edges along the injection-molded perimeter, so handle with gloves during installation. At the higher end of the cost spectrum, the included hardware and proven mileage improvement make this the most complete drop-in solution.
Why it’s great
- Includes all mounting screws and push rivets — no extra parts needed
- OE-composite material restores aerodynamic drag for fuel economy improvement
- Backed by over 100 years of Dorman automotive expertise
Good to know
- Sharp edges on the perimeter require careful handling
- Heavier than OEM plastic at 6.29 pounds
- Front center position only — does not cover rear areas
7. LQI Engine Splash Shield Cover
The LQI undercar cover is made from dense polypropylene (PP) plastic and replaces OEM numbers 74110-TR3-A10 and 74110TR3A10. It is compatible with 2012 Honda Civic non-Si trims and 2013 Acura ILX, but the description explicitly states it does NOT fit Civic MX or Si trims. This limits its use to LX, EX, and base models only — Si owners should skip this one unless they plan to modify mounting points.
The shield weighs 6.58 pounds and is designed for corrosion resistance against water splash. Several international buyers reported good fitment and ease of installation, though one reviewer noted the build quality felt “not as high” as the factory cover. Professional installation is recommended since no instructions are included.
If you own a non-Si Civic and need a low-cost PP replacement that matches the factory bolt pattern, this budget option works. For 2015 Civic Si owners specifically, the lack of Si compatibility and the weight premium make better options earlier in this list more appropriate.
Why it’s great
- Very affordable entry-level price for base Civic trims
- PP material resists water corrosion effectively
- Replaces OEM part number 74110-TR3-A10 for direct fitment
Good to know
- Explicitly not compatible with Civic Si or MX trims
- Heavier than OEM plastic at 6.58 pounds
- No installation instructions included
