Product Details

The Honda OEM Valve Cover Hex Cap Nut is a genuine factory replacement designed to secure the engine's valve cover trim, spark plug cover, or decorative engine cover on compatible Honda and Acura vehicles. Featuring a 6mm hex cap nut design with a black factory finish, this genuine Honda fastener provides the correct OEM appearance and fitment for applicable engine cover mounting locations.

Commonly used on popular Honda K-series applications, including the 2002–2006 Acura RSX, 2002–2005 Honda Civic Si, Honda Accord, Honda CR-V, and Honda Element, this genuine Honda nut is an excellent replacement for damaged, stripped, corroded, or missing factory engine cover hardware.

The factory engine cover and spark plug cover help maintain a clean, finished appearance in the engine bay. Missing or damaged mounting nuts can prevent these covers from being properly secured, potentially resulting in unwanted movement, rattling, or an incomplete factory appearance.

Whether you're restoring an Acura RSX Type-S, rebuilding a K20/K24 engine, replacing a missing valve cover nut, or refreshing your engine bay, this genuine Honda OEM Hex Cap Nut provides a simple, factory-quality replacement.

Installation Notes

Before installation, inspect the engine cover, mounting stud, and surrounding components for damage or contamination.
Confirm that the replacement nut matches the original hardware and is compatible with your specific engine cover mounting location.
Position the engine cover or spark plug cover correctly over its mounting studs.
Carefully thread the new Honda OEM hex cap nut onto the stud by hand to prevent cross-threading.
Always follow the factory service manual for the correct installation procedure and tightening specification for your vehicle.
Avoid overtightening, as excessive force can damage the mounting stud, engine cover, or surrounding components.
After installation, verify that the engine cover is properly seated and securely fastened.
