Supertech BMW S38 Inconel Exhaust Valve - Set of 12

If you're rebuilding the top end of your high-performance BMW S38 engine, especially for track use or demanding applications, you'll want to consider these Supertech Inconel exhaust valves. These aren't your everyday valves; they're built from Inconel, a superalloy known for its exceptional strength and resistance to extreme heat and corrosion. This makes them a solid choice for engines that see a lot of abuse, like those in motorsport or heavily modified street cars.

The choice of Inconel for exhaust valves is critical because the exhaust side of the engine experiences much higher temperatures than the intake side. Standard steel can start to soften and deform under these conditions, leading to sealing issues and reduced performance. Inconel holds its shape and strength even when glowing red hot, ensuring a proper seal and consistent performance over time. This set includes 12 valves, enough for a complete engine rebuild. Supertech is a well-known name in performance engine components, and these valves reflect their focus on durability and high-temperature performance.

When installing these valves, ensure your valve guides are in excellent condition and properly sized for the new valves. It's also a good idea to have your valve seats re-cut to match the new valves for optimal sealing. This is a significant part of a performance engine build, and using the right components like these Inconel valves will pay off in reliability and performance under stress.
