VW 12V 2.8L VR6 PERFORMANCE FERREA VALVES
Rev higher, flow more, no worries. Give your VW VR6 12 valve engine the best performance possible with Ferrea's Performance engine valves developed from cutting-edge experience in Formula 1, Indy Car, NASCAR, Sprint Car, drag and road racing. This technology allows Ferrea to provide the highest level of performance and reliability for your street or race engine build.
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.
SOLD INDIVIDUALLY
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 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)
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.
