GSC Stainless Steel Intake Valve Set 37mm (+1mm) EJ20/EJ257

Description:
GSC set out to create the best performance, longest lasting Subaru oversize (+1) 37mm intake valves available to the aftermarket. Using advanced 3D design and simulation programs GSC created a stronger and higher flowing valve head design. GSC flow tests prototype valve heads to specific applications, making sure they have the highest flowing valve head available on the market today. The materials used by GSC have less valve distortion at the face than any of the tested designs. Less distortion allows better sealing under extreme conditions and more consistent performance thru the life of the valve.
