Specs At A Glance

Good To Know

Q: Why does the factory PCV valve fail on these models? A: The original plastic valve is prone to leaking under increased turbo boost pressure, leading to boost leaks and excess oil consumption.

Q: Is this component compatible with naturally aspirated engines? A: No, this heavy-duty valve is engineered specifically for twin-turbocharged engines that experience positive crankcase pressure.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
