This sport intake valve for Opel CIH engines is designed for performance and high thermal durability. With a 45 mm valve head diameter, it is ideally suited for performance-enhanced engine setups in both road and motorsport applications.
The weight-optimized design reduces the moving mass in the valvetrain, improves response at high engine speeds, and increases high-RPM stability. The polished valve head and the flow-optimized, tapered valve stem enhance cylinder filling and improve gas dynamics within the intake port.
Specially hardened and surface-treated for maximum durability under high thermal and mechanical loads.
