MRP 4age 20v Stainless Steel Valve Set
These are our own custom made 1 piece solid valves
Stainless Steel EV8 (21-4N) Intake Valves
Stainless Steel EV16 Exhaust Valves for greater strength at higher temperatures (suitable for turbo applications)
Swirl polish finished
Very strong and will hold up to turbo applications using big boost 30psi+
We have found the +1mm OS Supertech valves are too weak for a turbo application on the exhaust side.
They break the heads off dropping the valves into your cylinder thus destroying your engine.
Great upgrade and will increase head flow even on a stock head
Oversize +0.5mm leaves more seat material for better heat transfer over a 1mm oversize valve – Out of Stock
Standard OEM size also available – Use the Drop Down List
