Supertech Subaru EJ20/25 Turbo DOHC Single Groove Inconel Exhaust Valve - Set of 8

If you're rebuilding the top end of a Subaru EJ20 or EJ25 turbo engine, these Supertech Inconel exhaust valves are a solid choice for handling the heat. This set includes eight valves, designed to replace the stock exhaust valves in your DOHC engine.

Inconel is a nickel-chromium-based superalloy known for its exceptional strength and resistance to high temperatures and corrosion. This makes it ideal for exhaust valves, which are subjected to the hottest gases in the combustion chamber. These valves feature a single groove design, compatible with many common valve spring setups. Their robust construction helps ensure consistent performance and durability under demanding conditions, especially in turbocharged applications where exhaust gas temperatures can get very high.

When installing these valves, ensure you have the correct valve spring retainers and seals for your specific engine build. Proper installation is key to maximizing their performance and longevity.
