Honda 2006–2011 Civic Si ECU Cover (37823-RNA-A00)
Bring your engine bay back to that clean OEM look with this Honda Civic Si ECU cover, part number 37823-RNA-A00. This isn’t a universal panel—this is the real Honda 37823-RNA-A00 cover that fits the 2006–2011 Honda Civic Si exactly like the original. If your stock Civic Si engine ECU cover faded, cracked, went missing, or turned into a sticker billboard, this is how you reset the bay and start fresh.
This 8th gen Civic Si ECU cover locks into the factory mounting points and sits tight over the ECU, so it actually protects your engine computer instead of just hiding it. You get proper Honda Civic ECU protection from dirt, debris, and moisture, plus a much cleaner layout when you pop the hood. Whether you’re refreshing your daily, cleaning up for a show, or bringing a modded 8th gen back to a factory-style bay, this Honda OEM ECU cover gives you the tidy, stock finish you forgot your car used to have.
