It’s Time to Ditch Those Nasty Yellow Caps

It’s a simple fact: the yellow OEM Subaru engine bay caps are just plain UGLY. They don’t match anything around them and they stick out like a sore thumb whenever your hood is popped. We aimed to come up with a solution to maintain the simplicity of the OEM plastic caps while blending in better with all of the other red and black GrimmSpeed parts under your hood. Best of all, these kits are a fraction of the price of aftermarket billet aluminum caps!

The GrimmSpeed Engine Bay Cap Set completely replaces the OEM yellow caps under the hood of all 2008-21 WRX and STI models, as well as most of the caps on early chassis’ as well. Available in either black or red, each kit includes 6 caps to accommodate nearly all Subaru fitments: Brake Master Cylinder, Clutch Master Cylinder, Coolant Overflow, Power Steering, and 2 different Washer Fluid Caps. All are made from a high-quality plastic that’s as durable as OEM, but looks MUCH better when installed.

INSTALLATION

Our Caps install in seconds – it’s as simple as removing the factory pieces and popping The GrimmSpeed versions in their place!

*For the Power Steering (08-14 WRX, 08-21 STI) and Clutch Master (02-14 WRX, 04-14 STI), our caps reuse the factory insert to ensure a proper seal. The insert will simply need to be removed and transferred from the factory cap onto the GS replacement.
