Unrestricted airflow. Built for boost.
The factory TGV (Tumble Generator Valve) system in FA20 engines is restrictive by design. It uses butterfly valves in the intake path that become a bottleneck once you start pushing airflow especially when you turn up the boost.
Roo Racing FA20 Billet TGV Deletes replace the entire TGV assembly with smooth, CNC-machined billet aluminium blocks, removing the internal valves completely and creating a straight, unrestricted path into the cylinders.
The result is improved airflow, better charge delivery, and a cleaner intake path under all conditions.
