This is for a full set of 8 Supertech performance +1MM Inconel exhaust valves! These feature the single groove valve keepers, for 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.
These are a great starting point for any 1.8t cylinder head build. 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. the Inconel valves are much more resistant to heat, so they are great for turbo and nitrous applications. We recommend these +1MM oversized valves for high horsepower applications. Every bit of extra flow helps tremendously. Machine work is required!
This is for a set of 8 Supertech +1MM Inconel exhaust valves, with 16 single groove valve keepers.
