This is for a full set of 8 Supertech performance exhaust valves!nnThese are a great starting point for any 1.8t 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. The inconel exhaust valves offer far superior reliabilty to OEM style stainless, sodium filled exhaust valves which often crumble into the cylinder. For the very highest performance builds, we can also supply these valves in +1mm oversize for maximum flow (machine work required). Also, single groove keeper setups are available for extremely high rpm usage. This setup grips the actual shaft of the valve, rather then relying on the material of the three grooves itself to restrain the valve.nThis is for a set of 8 exhaust valves. Options are available to suit your build.
