Radium Catch Can Kit for '01-'06 BMW M3 Base

An oil catch can is essential on a performance vehicle to protect the engine from elevated levels of crankcase blow-by accumulated from aggressive driving. Excess oil saturated air circulating back into the air intake stream can lead to degraded performance. Unlike many catch cans on the market, this catch can features an integrated oil separator that accelerates oil condensation.
