Includes both CCV and PCV catch can kits. All fittings, adapters, hoses and brackets are included. No permanent modification to the vehicle is required. The PCV catch can kit runs inline between the ventilation valve and the intake pipe. It mounts to threaded bosses on the front radiator support. This location stays clear of 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.
