GSC Power-Division 2015+ WRX FA20DIT +1mm Intake Valve Set of 8 Forced Induction The Exedy cerametallic friction material

The Exedy cerametallic friction material can handle much more abuse than stock type disc assemblies without slipping and fading

Stronger than tubing

But Tomei 4-1 type exhaust manifold has high efficency

Intake valves are a modified 21-4n stainless and exhausts are a modified 23-8n stainless material for high heat capacity while maintaining longevity

The IP69K rating provides protection against high pressure water at high temperature spray downs

GSC Power-Division 2015+ WRX FA20DIT +1mm Intake Valve Set of 8 Forced Induction The Exedy cerametallic friction materialStem Diameter (mm) 5. 5mm Overall Length (mm) 105. 00mm Head Diameter (mm) 35. 00mm When creating our new valve line we set out to create the best performance, longest lasting valves available to the aftermarket. Using advanced 3D design and simulation software, we have created a stronger and higher flowing valve head design. We flow test prototype valve heads in the specific applications to make sure we have the highest flowing valve head available
