Upgrading the valves in your VW or Audi engine increases reliability with slow forging processes, upgraded aerospace alloys, CNC machining, and heat treatments to withstand extreme abuse from high-powered race engines and daily driven road vehicles making beyond factory power levels. The power an engine produces is limited to airflow. As the smallest chokepoint in your cylinder head, performance valves are engineered to increase airflow by limiting turbulence created by valve stem obstruction and careful detailing of the valve head and valve angles.\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e \u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eOptional Single or Triple Groove Valve Keepers (Sold Separatly)\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eSupertech performance valves feature optional “radial-style” single groove on the valve stem and require matching single groove valve keepers. Single groove valves are preferred for performance orientated and race engines as the top part of the groove provides a cushion for the lock and aids in valve stem protection against uncontrolled and excessive valve movement. In addition, the single groove design greatly extends valve stem life by restricting rotation of the valve preventing accelerated wear by excess movement caused by the factory triple groove design.

Performance valve springs feature higher spring rates reducing the chance of valve float and engine damage at higher RPM. Titanium retainers reduce mass allowing the valve train to rev higher, faster. The use of titanium provides an adequate fatigue life to be acceptable for all but the highest mileage street use.

Using high-quality steel alloy also provides the added benefit of a better structural memory of the spring. The valve springs are computer designed to ensure that wire stress levels do not overpass the limits of stress defined in the diagrams of fatigue. This software also allows Supertech to ensure that the harmonics are under control, this advanced technology is combined with high-quality steel alloy making Supertech valve springs more durable in extreme conditions.
