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 1.8T 20V (058 \u0026amp; 06A) and 2.7T 30V engine valves are sold individually, add the correct amount of intake and\/or exhaust valves in the options you desire before adding to cart.\u003c\/p\u003e\n\u003ch2\u003eREQUIRED AMOUNT OF VALVES BY ENGINE:\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eALL 1.8T 20V (06A \u0026amp; 058)\u003c\/strong\u003e \u003cbr\u003e12 intake \/ 8 exhaust*\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAll 2.7T 30V\u003c\/strong\u003e \u003cbr\u003e18 intake \/ 12 exhaust*\u003c\/p\u003e\n\u003cp\u003e\u003cem\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\/em\u003e\u003c\/p\u003e\n\u003ch2\u003eSINGLE GROOVE VALVE KEEPERS \u003c\/h2\u003e\n\u003cp\u003eiE Spec Supertech performance valves feature “radial-style” single grooves on the valve stem and require matching single groove valve keepers. Single groove valves are preferred for street performance and race engine builds as the top part of the groove provides a cushion for the lock and aids in the 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. \u003cstrong\u003eSold individually, 2 keepers required per valve\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eREQUIRED AMOUNT OF KEEPERS BY ENGINE:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e1.8T 20V\u003c\/strong\u003e\u003cbr\u003e24 keepers required for intake and\/or 16 exhaust (40 required for a full engine, intake \u0026amp; exhaust)*\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e2.7T 30V\u003c\/strong\u003e\u003cbr\u003e36 keepers required for intake and\/or 24 exhaust (60 required for a full engine, intake \u0026amp; exhaust)*\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003e*Keepers are sold individually; each valve requires two keepers.

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. \u003cstrong\u003eOversized valves are not a direct installation.\u003c\/strong\u003e\u003c\/p\u003e\n\u003ch2\u003eVALVE STEM SEALS\u003c\/h2\u003e\n\u003cp\u003eMatch your performance valves to a set of IE Performance Valve Stem Seals.

This high-grade steel provides the strength to withstand the abuse from high-powered, high-revving, and turbocharged applications. The stainless steel valve is finished with Black Nitride Coating, a treatment that features harder surfaces and smoother finishes, providing less friction and, subsequently, longer life.\u003c\/p\u003e\n\u003ch2\u003eINCONEL EXHAUST VALVES \u003c\/h2\u003e\n\u003cp\u003eInconel material provides the highest level of exhaust valve reliability.
