    SUPERTECH exhaust valves are machined from a forged blank on CNC equipment for optimal precision. They then receive a heat treatment (which varies according to the valve's application) and are ground again (super-finishing process). SUPERTECH valves are checked by various means such as ultrasound, X-ray and laser measurement.

    For more than three decades, SUPERTECH has worked to find the most suitable materials for each valve and each application in order to increase reliability. There are therefore different valve materials such as stainless steel, Inconel, titanium and sodium (the latter present in the valve stem, for better heat dissipation).

    Note: these are the exhaust valves for the S14. For the matching SUPERTECH intake valves for the same engine, see: Reinforced Intake Valves BMW M3 E30 S14B23 S14B25.
