Grimmspeed Subaru Engine Bay Reservoir Cap Set - Red (Set of 6) - 120070 Female NPT Couplers NOTE: H2004SP1051 is the sameIt'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!
