GrimmSpeed 08-21 Subaru STI Boost Control Solenoid Cover - Red

GrimmSpeed engine dress-up pieces have been extremely popular with Subaru owners over the years, but there’s always been one small piece missing: Introducing The GrimmSpeed Boost Control Solenoid Cover for the 08-2021 Subaru STI!

We decided on a subtle design for this cover that mimics the “vent” styling on our matching GrimmSpeed Alternator Cover. Is it made from a single piece of lightweight aluminum with a laser cut GS logo for you to proudly represent your favorite aftermarket performance parts company! The piece is machine cut and bent for perfect OE-style fitment and is incredibly easy to install.
