Valve Set Supertech Exhaust Valve Set +1.8mm 12v VR6

These are a great starting point for any 12V VR6 cylinder head build. High quality forged stainless valves are black nitrated for maximum hardness and smoothness. For the price, these are an excellent replacement for stock valves. This is an exhaust valve set for the very highest performance builds. These valves are +1.8MM oversize for maximum flow (machine work required). These valves are back cut for flow and black nitrided to reduce friction and increase durability. This is for a set of 6 Supertech +1.8MM oversize exhaust valves.
