Supertech BMW S63 V8 32v 29mm(std) x 5.95 x 106mm Inconel Sodium Filled Exhaust Valve - Set of 16

This is a set of 16 Supertech Inconel sodium-filled exhaust valves, specifically made for BMW S63 V8 engines. These valves are a critical component for the high-performance demands of these powerful engines, handling the extreme heat and stress of combustion. If you're rebuilding the top end of your S63, especially if you're pushing the limits or looking for a robust replacement for worn-out factory parts, these valves are built to handle the job.

What sets these valves apart is their construction. They are forged from Inconel, a superalloy known for its exceptional strength and resistance to high temperatures and corrosion. This makes them ideal for exhaust applications where temperatures can soar. Inside, they feature sodium filling. The sodium core absorbs heat from the valve face and transfers it to the valve guide, helping to keep the valve head cooler. This improved thermal management is key to preventing valve seat recession and maintaining performance under sustained high loads. The valves measure 29mm in standard diameter, with a 5.95mm stem and a 106mm overall length, designed to be a direct fit for the S63 engine's valve train.

When installing these, it's important to ensure your valve guides are in excellent condition and properly sized for the 5.95mm stems. Proper valve seat conditioning and assembly are also crucial for optimal performance and longevity. This set includes all 16 exhaust valves needed for a complete V8 engine rebuild, offering a well-built solution for enthusiasts looking to maintain or enhance their BMW's engine reliability and performance.
