Furthermore, the closed system prevents unwanted oil vapors from entering into the cabin.  FEATURES-Effectively raises the octane and increased engine performance from cleaner inlet air-Prevents oil buildup in the intake or intercooler system walls, throttle body, intake manifold, etc.-Excessive oil collection can be an indicator of a damaged engine.-Lowers hydrocarbon emissions-Capacity: 7 fluid ounces 20-1337-FL CATCH CAN ADD-ON, CCV, 98-05 MAZDA MX-5, FLUID LOCK NOTE: THIS ADD-ON CANNOT BE INSTALLED WITHOUT 20-1336-FL CATCH CAN KIT The anodized aluminum catch can bracket mounts to the catch can bracket included with 20-1336-FL.  To retain factory functionality, the CCV catch can runs inline between the crankcase vent (CCV) port and the intake pipe. At low loads, this catch can experiences atmospheric pressure. However, when the engine is at high load (WOT), the catch can will experience high flow out of the crankcase. This would normally lead to oil and sludge accumulation throughout the intake system.
