Supertech Subaru H6 (w/Variable Intake Lift) Inconel Exhaust Valve - Set of 12

Supertech is well-known for making high-performance engine components, and these Inconel exhaust valves are a prime example of their work. If you're rebuilding the top end of a Subaru H6 engine that features Variable Intake Lift, these valves are built to handle the demands of high-performance operation. They are specifically designed to replace the stock exhaust valves, ensuring a proper fit within the cylinder head.

The key feature here is the Inconel material. This is a high-nickel, high-chromium alloy that's incredibly resistant to heat and corrosion. In an exhaust valve, this translates to much longer life and consistent performance, especially in engines that see high temperatures or are subjected to aggressive driving. Because they are made from Inconel, these valves can withstand the extreme conditions found in the exhaust port, helping to prevent premature failure and maintain sealing integrity over time. This set includes 12 valves, enough to replace all the exhaust valves in your H6 engine.

When rebuilding an engine, using high-quality internal components like these Inconel valves is crucial for reliability and performance. Make sure to consult your engine's service manual for the correct installation procedures and any specific requirements for valve seating and break-in.
