RCM 12 MM MODIFIED SUBARU OIL PUMP
12MM Oil pump is recommended for Dual AVCS Engines.
At the heart of all Roger Clark Motorsport engine builds is the now world-renowned RCM Modified oil pump. This clever, effective modification has been designed to assist the Impreza with its oil supply issues and is now regarded as a "must-have" modification with any Impreza engine build. Each pump is carefully checked, given a serial number and then modified to incorporate a different pressure relief valve ensuring greater reliability and peace of mind to your Impreza engine.
Please note that flow rate remains unchanged.
Oil pumps are supplied with a replacement front crank oil seal and oil gallery, black sealing o-ring. It is also recommended that you use 3 bond sealer (SGA35) to seal the oil pump to the block assembly.
