Bundle and SAVE!  Choose your color combo to dress up your engine bay!

The Precision Raceworks Billet Engine Cap Set is a functional and stunningly  stylish way to add a nice touch to any engine bay!

These caps come in three color options so there is always a color that will work for you! Black with Billet, Black with Blue, and the Stealth series (all black).

Many people don't realize it but the OEM caps have a pressure release valve built into them.  Often times aftermarket companies don't know this either or just don't care.  But our team cares about proper function just as much as we care about the appearance in every product we design. For pressure relief, our caps incorporate the OEM internals, so you get all the functionality of the original caps, ensuring a safe and reliable system in place.

These caps offer superior style and performance-grade components that replace the factory cap not just cover it up. The durable billet aluminum construction provides long-lasting protection and dependability that will upgrade your engine bay for years to come!




These do require assembly and swapping the pressure relief valves from your old caps to your new billet caps.

These are beautiful not just taped on pieces of metal. They use the internal parts from the OEM equipment, plus they come in three color ways.
