M7 Speed "Exact Fit" Oil Catch Can

The MINI Cooper S is prone to excessive oil vapor within the intake system from the positive pressure induction system from the factory. Once installed, the M7 catch can separates the oil vapors from the crankcase air before it is returned back into the intake charge, keeping your intercooler and sensors working at peak performance. If you've ever taken off your intercooler, you most likely noticed a build up of oil within each rubber boot sealing each end of the intercooler. Spray some cleaner into it and you'll quickly discover massive amounts of oil that build up inside the intercooler! This oil coating is not in itself harmful to the general operation of the engine, but it does affect the performance by limiting the efficiency of the intercooler in cooling the compressed intake charge -- not to mention gumming up various sensors and components including the critical intake valves.
