Peugeot / Mini 1.6L Turbo EP6 Supertech (Single Groove) Black Nitrided Intake Valve Set

Supertech Black Nitride Intake Valves offer enhanced durability and reduced friction, ideal for high-performance engines.

Made from high-grade EV8 (21-4N) stainless steel with a proprietary black nitride coating, these valves provide a harder surface, increased wear, and corrosion resistance.

The coating also improves valve motion efficiency by reducing friction and wear, leading to a longer lifespan and potential power gains, especially at higher RPMs.
