Ryansunoro Engine Splash Shield for Honda Civic 2016-2021 — Aluminum Alloy Front Underbody Guard with Mounting Hardware

Ryansunoro’s aluminum alloy engine splash shield is a lightweight, corrosion-resistant front underbody guard made to protect the underside of Honda Civic models from 2016 through 2021.

This front engine splash shield (compatible with OEM numbers 74110-TBA-A00 and 90674-TY2-A01) replaces the factory plastic guard with a tougher magnesium-aluminum alloy panel that resists rust, sheds debris, and helps block water and mud from reaching critical engine components. It’s engineered for a near-factory fit to the Civic chassis and ships with the matching mounting hardware and gloves to simplify installation.

How does this shield protect my Civic in everyday driving?

The Ryansunoro shield creates a barrier under the engine bay that absorbs impacts from road debris and deflects stones, slush, and spray. Its rigid alloy construction reduces the chance of punctures and tearing that can happen with thin plastic guards.

• Guards oil pan, belts, and lower engine components from direct hits.
• Prevents mud and water spray buildup that can corrode or clog parts.
• Alloy build resists deformation better than OEM plastic panels.

Will this fit my Honda Civic 2016–2021 and match OEM mounting points?

Yes — the panel is designed to fit Civic models from 2016 through 2021 and is intended as a direct replacement for OEM reference numbers 74110-TBA-A00 and 90674-TY2-A01. The shape and mounting hole pattern align with factory attachment points for a secure fit.

• Designed to match OEM hole layout for bolt-on installation.
• Includes the mounting hardware needed for most installations.
• Trimmed profile to clear suspension and steering components.

What material is used and why does it matter?

The shield is fabricated from a magnesium-aluminum alloy chosen for corrosion resistance, structural strength, and light weight. Compared with heavier steel or thin plastics, this alloy provides long-term durability without a significant weight penalty.

• Magnesium-aluminum alloy resists rust and long-term degradation.
• Lightweight design helps maintain fuel efficiency and handling balance.
• Stiffness improves impact resistance versus stock plastic shields.

How easy is installation and what comes in the box?

Installation is straightforward: the shield uses factory-style mounting points and includes all necessary hardware plus a pair of gloves for handling. Typical installation requires basic hand tools and can be completed in a garage or on a lift in under an hour for most DIYers.

• Comes with matching bolts, clips, and installation gloves.
• No trimming or special tools required for standard Civic models.
• Instructions and customer support available if any questions arise.

Who this is for: Drivers who own a Honda Civic model year 2016–2021 and want a robust, corrosion-resistant upgrade to the factory under-engine shield. It’s aimed at people who frequently drive on rough roads, in coastal areas, or in climates where road salt and debris are common, plus DIY owners who prefer a durable, bolt-on replacement that preserves underbody protection without adding significant weight.
