Product Description

The catch can mounts in the RH compartment of the engine bay near the firewall. Thus, it is not compatible with RHD models. It is compatible with early models where the ABS module is mounted in this compartment. It is also compatible with later models that have a secondary PCV system.

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.
