Product Summary
Details

LEADING FEATURES

  • 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 

 

WHAT IS A PERFORMANCE VALVE?

Valves play a critical role in any performance orientated engine. Upgrading the valves in your VW VR6 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.

 

VALVES SOLD INDIVIDUALLY

Supertech 12V VR6 engine valves are sold individually, add the correct amount of intake and/or exhaust valves in the options you desire before adding to cart.

REQUIRED AMOUNT OF VALVES BY ENGINE:

  • All 2.8L 12V VR6 engines: 6 intake valves and/or 6 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.

 

OVERSIZED VALVE OPTION (REQUIRES 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.

 

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 FSI: 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 VALVES (INTAKE & EXHAUST)

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 Blake Nitride Coating, a treatment that features harder surfaces and smoother finishes, providing less friction and subsequently longer life.
