Supertech BMW S65 V8 / S85 V10 Inconel Exhaust Valve - +2mm Oversize - Single

If you're rebuilding the top end of your BMW S65 V8 or S85 V10 engine, especially for high-performance applications, you'll want to consider these Supertech Inconel exhaust valves. They are designed to handle the extreme temperatures and pressures found in these powerful V8 and V10 engines.

These valves are made from Inconel, a well-known superalloy that offers exceptional resistance to heat and corrosion. This makes them a strong choice for engines that see a lot of track time or aggressive driving. The +2mm oversize design means they are larger than stock, which can help improve airflow and potentially boost performance when paired with other engine modifications. They fit right into the stock valve seats, making them a straightforward replacement during a rebuild.
