K-series K20 Type-S Oil Pump

Genuine Honda OEM Honda / Acura 15100-PRB-A01 Oil Pump Assembly. This is the OEM pump for '02-'06 RSX-S (K20A2 & K20Z1), and JDM K20A EP3/DC5 engines.

This is also an extremely popular upgrade to replace the heavy stock K-Series oil pumps on the K24A & K20Z3 engines that have balance shafts and struggle to maintain sufficient oil pressure at high rpm. The K20A2 PRB oil pump frees up horsepower and is more efficient at higher RPMs. 

This is just the oil pump not a kit.
