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.
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:
*Valves are sold individually, be sure to order the correct amount of intake and/or exhaust valves as needed for your engine application.
Ferrea 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.
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.
Ferrea's Competition Plus Intake Valve are reliable and extreme duty valve option for the 24V VR6 engines for both N/A or boosted applications. 2-step slow forged from special aerospace quality EV8-Z18 alloys eliminates material structural damage and provides proper grain flow with extremely reliable high-tensile strength. Each valve is heat-treated and stress-relieved over a 48-hour period for molecular integrity and feature avionics-quality hard chrome along with a specially applied hard tip.
Ferrea's Super Alloy exceeds typical Inconel alloy and is highly recommended for exhaust valves in turbocharged or boosted 24V VR6 engine builds. Super Alloy is the absolute highest level available in exhaust valve technology. Engineered to handle extreme heat requirements and punishment from turbocharged engines running high boost, nitro fuels, nitrous oxides, ethanol, and pump gas. Reversed forged for superior strength and durability, the Super Alloy can withstand exhaust gas temperatures exceeding 2400 degrees Fahrenheit onto the valve. Every valve is finished with a refined swirl and micro polish to eliminate surface imperfections. Ferrea's valves have been used in Top Fuel and Funny Car applications and can confirm the performance and reliability of Super Alloy Valves in the most demanding and volatile situations. Put that same level of reliability in your own 24V VR6 engine build.
