Radium Engineering/s closed loop system does NOT vent to atmosphere (VTA), thus is emissions and track legal. Instead, clean filtered air routes back in through the engine to be burned and to promote negative crankcase pressure for optimal performance. Furthermore, a closed system prevents unwanted oil vapors entering into the cabin. FEATURES Effectively raises fuel octane and increases performance with cleaner intake air Prevents oil buildup in the throttle body, intake, manifold, etc. Excessive oil collection can be an indicator of a damaged engine Stainless steel filtration media is cleanable and reuseable Lowers hydrocarbon emissions Capacity: 7 fluid ounces Height (without fittings): 5 inches Outside Diameter: 2.45 inches INCLUDES Billet aluminum oil catch can with integrated dipstick Laser cut anodized E46 specific mounting bracket Anodized aluminum 10AN hose ends and adapter fittings Anodized aluminum V2 quick connect 10AN adapter fittings Enough 10AN (5/8") PCV hose to work with modified vehicles Stainless steel mounting hardware and hose clamps
