Supertech Opel/Vauxhall C20XE / C20LET Inconel Exhaust Valve- +1mm Oversize - Single (D/S Only)

If you're rebuilding the top end of your Opel/Vauxhall C20XE or C20LET engine, especially for higher performance applications, you'll want to consider these Supertech Inconel exhaust valves. These are designed to handle the intense heat and stress that exhaust valves endure, making them a solid choice for performance builds.

The material here is Inconel, which is known for its exceptional heat resistance and strength, far beyond what standard steel valves can offer. This particular valve is a +1mm oversize option, meaning it's slightly larger than stock. This can help improve sealing and potentially airflow when used in conjunction with a valve job that accommodates the larger size. It's sold individually and is specifically for the exhaust side of the engine.

When installing these, make sure your valve guides and seats are in good condition and properly prepped for the oversize fitment. It's always a good idea to consult your engine's service manual for the correct installation procedures.
