This is a factory OEM Acura RSX Type-S K-series oil pump assembly that is a direct replacement pump for the 02-04 RSX-S (K20A2), 05-06 RSX-S (K20Z1), and JDM K20A DC5/EP3 engines.

Whether you're building a K20/24 or just rebuilding your stock K-series motor, the Type-S oil pump is the best and most reliable oil pump for the money. This oil pump is proven to provide oil pressure to 8600rpm and offers no parasitic drag unlike the factory oil pumps with integrated balance shafts found on all stock K24* engines, 06-11* Civic Si's (K20Z3), and 02-05* Civic Si's.

*Some modifications and extra parts are required to use a Type-S oil pump on these engines
