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