The TGV deletes are one of the easiest ways to eliminate the factory tumbler generator valves on your turbocharged Subaru FA20F DIT engine and it will increase flow to your engine by 25%. The other advantage by removing this failure prone part is to eliminate a lot of the carbon build up around that area that we are seeing upon removal.
AVO’s TGV Deletes are CNC machined from billet aluminium and anodized black for corrosion protection and feature an engraved AVO Logo. The TGV housings are a simple install which require a 10mm and 12mm socket, and flat blade screw driver and can be installed in approximately 30 to 45 minutes.
