GrimmSpeed Engine Bay Reservoir Cap Set RED - Subaru 02-21 WRX/STI/FXT/OBXT/LGT (120070) 5018 APR's engineering team went backIt'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 RED GrimmSpeed parts under your hood.
