Supertech Mini Cooper W11B16A 1.6L Supercharged Inconel Exhaust Valve- +1mm Oversize - Set of 8

Supertech is known for making well-built engine components, and these Inconel exhaust valves are a prime example. If you're rebuilding the top end of a Mini Cooper with the W11B16A 1.6L supercharged engine, these valves are designed to handle the heat and stress of that setup. They are a +1mm oversize, which can be beneficial for improving sealing and performance when paired with updated cylinder head work.

These valves are made from Inconel, a high-nickel alloy that's incredibly resistant to high temperatures and corrosion. This makes them a solid choice for exhaust applications where extreme heat is a constant factor, helping to prevent valve distortion or failure over time. The set includes eight valves, all precisely manufactured to ensure they fit right and perform consistently. The +1mm oversize dimension means they are slightly larger than stock, which can help achieve a better seal against the valve seat, especially if the seats have been reconditioned or replaced.
