The Process West Billet TGV Delete Kit removes the factory tumble generator valves on Subaru EJ20 and EJ25 engines to reduce intake restriction. This is the 67mm-length kit, the one needed when fitting a Process West billet plenum to a GC8, and Process West also makes a 79mm length. The port profile is machined to suit ported cylinder heads, and the O-ringed upper flange seals against factory and aftermarket plenums. The injector ports take 11mm or 13mm injectors with the supplied Viton O-rings, the fuel rail mounting points match factory specification, and the kit comes in silver or black.
