Push your VW or Audi 2.0T FSI, TSI, or 2.5L cylinder head to the limits with Supertech Performance engine valves. Supertech combines over 30 years of racing experience with state-of-the-art equipment and manufacturing processes to bring you strong and reliable valve options for your race or street engine build.

Please Note: Supertech 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.

2.0T FSI
8 intake valves and/or 8 exhaust valves*

2.0T TSI
8 intake valves and/or 8 exhaust valves*

2.5L 5 Cylinder
10 intake valves and/or 10 exhaust valves*

*Valves are sold individually, be sure to order the correct amount of intake and/or exhaust valves as needed for your engine application.

What Is A Performance Value

Valves play a critical role in any performance-orientated engine. 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.

Optional Single or Triple Groove Valve Keepers (Sold Separatly)

Supertech 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. Sold individually, 2 keepers required per valve.

REQUIRED AMOUNT OF KEEPERS BY ENGINE:

2.0T FSI 
16 keepers required for intake and/or exhaust (32 required for a full engine, intake & exhaust)*

2.0T TSI 
16 keepers required for intake and/or exhaust (32 required for a full engine, intake & exhaust)*

2.5L 5 Cylinder 
20 keepers required for intake and/or exhaust (40 required for a full engine, intake & exhaust)*

*Keepers are sold individually, each valve requires two keepers. Be sure to order the correct amount of valve keepers as needed for your engine application.

Please see the following links for the individual Valve Keepers:

•  6mm Single Groove Valve Keeper
•  6mm Triple Groove Valve Keeper  

Optional Oversized Valve Option (Require Machine Work)

Supertech valves are available in either standard factory size or oversized valve head diameters. 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.

+2mm oversized valves require aftermarket valve seats, stock seats cannot be machined to fit +2mm oversized valves. Ensure you have access to aftermarket performance valve seats before ordering +2mm oversized valves.

Valve Stem Seals

Match your performance valves to a set of IE Performance Valve Stem Seals. Manufactured from heat-resistant Viton for use with the exhaust valves and high-quality polyacrylic for intake valves. These superior quality materials ensure longer valve seal life on higher output engines producing beyond stock power levels. Sold individually.

REQUIRED AMOUNT OF VALVE SEALS BY ENGINE:

2.0T FSI 
8 intake seals and/or 8 exhaust seals*

2.0T TSI
8 intake seals and/or 8 exhaust seals*

2.5L 5 Cylinder
10 intake seals and/or 10 exhaust seals*

*Valve seals are sold individually, be sure to order the correct amount of intake and/or exhaust seals to match your valve purchase.

Stainless Steel Intake Valves

Supertech's intake valves are made exclusively from enhanced EV8 (21-4N) steel. 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.

Inconel Exhaust Valves

Supertech's Inconel exhaust valves are manufactured from a nickel-based alloy material providing incredible temperature distribution that lowers temperatures across the entire cylinder head. Inconel valves are perfect for engines that reach very high exhaust gas temperatures found in both street and race turbocharged engines.

• Improved airflow via application-specific CNC machining
  
• Maximized fatigue resistance and tensile strength
  
• Valve tip is hardened beyond 52HRc
  
• Strict dimensional tolerances for improved sealing
  
• Superfinished to reduce surface roughness
  
• Optimized high flow rate designs
