Install Splash Guards on a Civic Si Coupe

Quick Answer

Install the Genuine Honda Civic Si Coupe Splash Guards without drilling using the included hardware. The job takes about 30 minutes and requires only basic hand tools.

Step-by-Step Installation Guide

1. 1. Park and Prepare: Park on a level surface and turn the wheels to one side for better access to the wheel well. Clean the area behind the wheel where the splash guard will mount. A common mistake is skipping the cleaning step—dirt and debris can prevent the guard from sitting flush.
2. 2. Remove Factory Push Pins and Screws: Use a trim removal tool or taped flathead screwdriver to pop out the lower push pins in the wheel well liner. Remove the two 10mm screws at the bottom edge of the bumper. Keep all hardware in a cup; you will reuse the screws and some pins. Losing them means a trip to the hardware store.
3. 3. Position the Front Splash Guard: Align the front splash guard over the wheel well opening. The guard should sit flush against the bumper and liner. Insert the two screws through the guard into the original bumper holes and tighten by hand. Do not overtighten—the plastic guard can deform. Snug is enough.
4. 4. Secure the Front Guard with Push Pins: Reinstall the lower push pins through the guard into the wheel well liner. Press firmly until they click into place. Repeat for the other front wheel. If a push pin does not seat fully, check that the guard is not misaligned. Forcing it can break the pin.
5. 5. Install the Rear Splash Guards: For the rear, locate the existing holes in the bumper cover behind each rear wheel. Position the guard and insert the two screws into the top holes. Then secure the lower edge with the provided push pins. The rear guards are symmetrical but not identical—check the left and right markings on the plastic before installing.
6. 6. Final Check and Test Fit: Turn the wheels to full lock in both directions to confirm no rubbing. Verify all fasteners are tight and the guard sits evenly against the body. If you hear rubbing after driving, recheck alignment. A guard touching the tire can wear through the plastic quickly.
