Subaru WRX/STI 2006-2007 Engine Cap Set



Cleanup Your Engine Bay with our 06-07 WRX/STI engine dress up kit! Now includes our cooler running Delrin hybrid oil cap! Made to order. Unless specified IN STOCK delivery can take up to 8 weeks.



Introducing a track tested, CNC machined full replacement engine bay cap set to add to your build theme and increase engine bay aesthetics

Now Includes our exclusive Aluminum Delrin hybrid oil cap!
This cap consists of a billet Aluminum top piece and a Delrin thread insert that resists heat conduction from the block. The result is a cap that perfectly matches the rest of our set while remaining significantly cooler than an all Aluminum cap.

The Renegade Motorsports 06-07 WRX/STI cap set completely replaces the OEM yellow plastic caps, giving your engine bay a clean and styled look. The 06-07 WRX/STI Base set includes the following caps: oil, brake, clutch and power steering. The coolant overflow and wiper caps can also be added to the set depending on your application. All of our caps are machined in house out of 6061-T6 Aluminum. Additionally, our engine oil cap is made using Delrin-Aluminum hybrid to effectively reduce heat transfer.


We made these caps to go on tight and stay on. You will love how snug and firm the caps feel once installed. The final alignment was not something we overlooked either, the caps are all designed to be aligned facing the front of the vehicle when tightened into place. The oil cap and the brake fluid cap utilize the OEM seals currently on your vehicle. Seals are provided for the wiper fluid and coolant overflow cap.


We currently offer the cap sets in blue, black and red anodize as our standard finishes. Many custom finishes available at an extra charge.

We’re happy to help you bring your vision to life!
