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.\u003c\/p\u003e\n\u003ch2\u003eVALVES SOLD INDIVIDUALLY\u003c\/h2\u003e\n\u003cp\u003eSupertech 2.0T FSI\/TSI and 2.5L 5 Cylinder engine valves are sold individually, add the correct amount of intake and\/or exhaust valves in the options you desire before adding to the cart.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eREQUIRED AMOUNT OF VALVES BY ENGINE:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e2.0T FSI\u003c\/strong\u003e \u003cbr\u003e8 intake valves and\/or 8 exhaust valves*\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e2.0T TSI\u003c\/strong\u003e \u003cbr\u003e8 intake valves and\/or 8 exhaust valves*\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e2.5L 5 Cylinder\u003c\/strong\u003e\u003cbr\u003e10 intake valves and\/or 10 exhaust valves*\u003c\/p\u003e\n\u003cp\u003e*Valves are sold individually, be sure to order the correct amount of intake and\/or exhaust valves as needed for your engine application.\u003c\/p\u003e\n\u003ch2\u003eREQUIRES SINGLE GROOVE VALVE KEEPERS, SOLD INDIVIDUALLY\u003c\/h2\u003e\n\u003cp\u003eThese Supertech performance valves feature a “radial-style” single groove on the valve stem and require matching single groove valve keepers to match. 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.

Larger diameter (oversized) valve heads provide an increased skirt area, resulting in further increased airflow at lower valve lifts for the maximum cylinder head efficiency at the valve port. Oversized valves require either aftermarket valve seats or machining to the factory valve seats for installation to match the larger diameter head, oversized valves are not a direct installation.\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003e+2mm oversized valves require aftermarket valve seats, stock seats cannot be machined to fit +2mm oversized valves.
