TomGoo Engine Splash Shield Guard for Honda Civic 2016-2021 — Aluminum Under-Car Engine Case Guard, OEM Fit

TomGoo Engine Splash Shield Guard is a precision-fit aluminum undercarriage cover designed to protect Honda Civic 2016–2021 engines from road debris, water, and abrasion while reducing noise and vibration.

This engine case guard replaces worn or damaged factory splash shields with a durable, corrosion-resistant aluminum alloy panel made to match OEM part numbers 74110-TBA-A00 and 90674-TY2-A01. It restores undercarriage protection, helps prevent oil pan and lower-engine contact with road hazards, and is engineered for an easy homeowner installation with included hardware and gloves.

How will this splash shield protect my Civic on everyday drives?

The TomGoo splash guard creates a barrier between the road and sensitive engine components, deflecting gravel, salt, and standing water away from the oil pan, belts, and electrical connectors. Its aluminum construction resists dents and corrosion better than thinner plastic alternatives, maintaining protection over time.

• Blocks stones, road spray, and salt from reaching the engine underside.
• Stiff aluminum resists punctures and deformation from impacts.
• OEM-matching fit reduces gaps that allow debris intrusion.

Will installing this guard change engine noise or ride feel?

Yes — the rigid panel helps dampen engine bay noise and reduces vibration that would otherwise transmit into the cabin, yielding a quieter, smoother driving experience. While not a substitute for dedicated sound deadening, it contributes a noticeable reduction in road and mechanical noise.

• Aluminum body lowers vibration compared with flimsy plastics.
• Closes open cavities under the engine that amplify sound.
• Improves perceived refinement at highway speeds.

How difficult is installation, and will parts fit my Honda Civic?

The panel is manufactured to align with the Civic’s factory mounting points for model years 2016–2021 and references OEM numbers 74110-TBA-A00 and 90674-TY2-A01 for compatibility. TomGoo includes bolts and gloves so many owners with basic tools can complete the swap in a driveway or garage in under an hour.

• OEM-compatible mounting locations for a secure fit.
• Included hardware and gloves speed up the replacement.
• Simple bolt-on process—no special tools typically required.

How does this guard help me save on maintenance and repairs?

By blocking impacts and corrosive road elements, the splash guard helps prevent damage that can lead to expensive oil pan, sensor, or wiring repairs. Its durable material reduces the need for frequent replacements compared with fragile aftermarket plastics.

• Prevents punctures and scrapes to vulnerable lower engine parts.
• Reduces corrosion from road salt and moisture exposure.
• Longevity of aluminum means fewer repeat replacements.

Who is this for? The TomGoo Engine Splash Shield Guard is aimed at Honda Civic owners (2016–2021) who want an OEM-fit replacement that improves protection and reduces noise without professional installation. It’s ideal for drivers who regularly encounter gravel roads, winter salt, parking-lot curbs, or who simply want a more robust undercarriage shield than factory plastic offers. Mechanics, DIY enthusiasts, and fleet operators who require durable, repeatable fit will appreciate the aluminum construction and included mounting kit.
