Having an oil catch can is essential on a performance vehicle. It is used to protect the engine from elevated levels of crankcase blow-by that can accumulate from aggressive driving on and off the race track. Without an oil catch can the engine is prone to having excess oil saturated air circulating back into the air intake stream which can lead to degraded performance. Unlike many catch cans on the marketRadium Engineering?s 6061 Billet Aluminum O-Ring Sealed Oil Catch Can is designed with an integrated oil separator that accelerates oil condensation and is completely cleanable and reusable. The liquid oil is collected in the reservoir and can be easily disposed without removing the can from its Laser cut and powder coated mounting bracket. The lower half of the oil catch can body unscrews with ease for draining or a Radium PETCOCK drain Kit can be installed if the cans cannot be easily separated due to space. Excessive oil collection can be an indicator of a damaged engineRadium integrated an easy-to-use 6061 Billet Aluminum dip stick for the convenience of checking the oil levels periodically.Features and Notes:Stainless Steel Cleanable and Reusable Filter MediaMain Ports: 7/8 Inch-14 Female Threads (-10AN O-Ring)O-Ring Sealed -4AN Drain PlugStainless Steel Mounting HardwareSafe for Pressurized Applications
