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 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.

 

SHORT & LONG VALVES, SOLD INDIVIDUALLY

Your 24V 3.2L VR6 engine uses a particular valve angle on both exhaust and intake side, this valve angle requires 6 short and 6 long valve stems per intake and exhaust. All 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:

  • Requires 6 intake long valves*
  • Requires 6 intake short valves*
  • Requires 6 exhaust long valves* 
  • Requires 6 exhaust short valves* 

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

 

REQUIRES SINGLE GROOVE VALVE KEEPERS, SOLD INDIVIDUALLY

Supertech's R32 VR6 valves feature "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:

  • All R32 VR6 Engines: 24 keepers required for intake and/or exhaust (48 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. Triple-groove valves reuse stock keepers. 

 

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, requires 12 intake and/or 12 exhaust valve seals. 

 

INCONEL VALVES (EXHAUST)

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. Iconel valves are perfect for engines that reach very high exhaust gas temperatures from large frame turbo engines found in both street and race applications.
