Fits Mini Cooper models equipped with N14B16 and N18B16 engines. These Supertech exhaust valves are engineered specifically for the extreme thermal environments found in high-performance turbocharged applications. Manufactured from Inconel, a specialized nickel-based superalloy, these valves maintain high tensile strength and resist oxidation at temperatures that would compromise standard stainless steel.

These valves feature a sodium-filled stem design, which provides a critical cooling mechanism by transferring heat away from the valve head through the stem and into the valve guide. This +0.8mm oversized set is ideal for cylinder heads with modified valve seats, offering increased surface area and improved flow characteristics for high-output N14 and N18 builds.

  • Material: Inconel Superalloy for extreme heat resistance
  • Feature: Sodium-filled stem for superior thermal dissipation
  • Size: +0.8mm Oversize (OS)
  • Engine Compatibility: N14B16 / N18B16
  • Manufacturer Part Number: MCEVI-1202-HS-8
  • Quantity: Set of 8 valves
