Supertech BMW S14 32.5 x 6.95 x 126.10mm Flat Blk Nitrided Exhaust Valve - Set Of 12

If you're rebuilding the top end of your BMW S14 engine, these Supertech exhaust valves are a solid option. This set includes 12 valves, each measuring 32.5mm in diameter, 6.95mm in stem size, and 126.10mm in overall length. They are designed as a direct replacement for your stock valves, making installation straightforward during your engine build.

These valves feature a black nitrided surface treatment. This process hardens the surface, which helps improve wear resistance and durability, especially under the high temperatures and stresses found in performance engines. The flat face design is standard for exhaust valves, ensuring a good seal against the valve seat.

When working on your S14, using well-made internal components like these valves is key to a reliable rebuild. Ensure you have the correct valve spring compressor and other necessary tools for proper installation. Refer to your engine's service manual for specific installation procedures and torque specifications.
