Tomei Over Size Valve Set - Nissan R35 GTR VR38DETT 20470SA011 correcting the geometry that deterioratedTuned engines require as much fuel mixture to enter the combustion chamber as possible. So a larger diameter design was selected to optimize flow rates. Due to the extremely high temperature conditions experienced, Intake, the combustion chamber during high power runs the durability of the valves were also addressed to improve resistance to high heat conditions. The TOMEI oversized valves were designed with the above factors and more so with the
