The CCV catch can mounts to 2 holes on the front radiator support. It was designed specifically to clear strut braces. This location mounts the catch can far forward to help prevent any interference with aftermarket parts such as an upgraded turbocharger or intake tubing. To retain factory functionality, the CCV catch can runs inline between the crankcase vent (CCV) port and the intake pipe. At low loads, it experiences atmospheric pressure. However, when the engine is at high load (WOT), the line will experience high flow from the crankcase into the intake system. This would normally lead to oil and sludge accumulation in the air filter intake pipe. This oil accumulation would spread and be found in the intercooler which lowers the thermal efficiency properties of the heat exchanger and leads to decreased performance. The CCV catch can captures this and promotes clean filtered air back into the intake.
