BMW 2.0L Turbo, Mini Cooper S B48B20 Supertech (Single Groove) Sodium Filled Exhaust Valve Set

Supertech sodium-filled intake valves, constructed from advanced Inconel alloy, are a premium performance component designed for high-output and turbocharged engines, offering significant temperature reduction, improved strength, increased durability, and lower overall weight.

The hollow stem contains sodium, which melts and circulates with valve movement, efficiently transferring heat away from the valve head to the valve guide, preventing extreme heat buildup and increasing valve life.

These valves provide tuners with greater flexibility, allowing for more aggressive spark timing and improved engine power potential in demanding applications.
