Product Details

The Supertech Performance SPRK-A2416N-V6 is a complete valve spring and titanium retainer kit designed specifically for Audi V6 2.9 TFSI and 3.0 TFSI 24-valve engines (EA839). This performance upgrade is engineered for high-RPM applications and allows safe operation beyond stock rev limits, making it ideal for drag racing, road racing, rally, and other motorsport applications.

Key Features:

  • Complete kit includes 24 valve springs (SPR-A2416N) and 24 titanium retainers (RET-A2416-N2)
  • Valve springs manufactured from premium chrome-silicon-vanadium steel alloy for maximum durability at high RPM
  • Computer-designed springs control wire stress levels and harmonics to prevent material fatigue under extreme conditions
  • Military-grade titanium retainers are CNC machined for precise fit and reduced valve train mass
  • Intake seat pressure: 73 lbs @ 37.40mm / Open pressure: 178 lbs @ 10mm
  • Exhaust seat pressure: 85 lbs @ 36mm / Open pressure: 190 lbs @ 10mm
  • Maximum lift: 11.00mm / Coil bind: 24.90mm / Spring rate: 10.5 lbs/mm
  • Outer spring diameter: 24.00mm / Inner diameter: 16.50mm

This kit enables safe operation up to 8,000 RPM with potential for higher RPM when used with solid lifter bucket conversion. The increased spring rates help prevent valve float while the lightweight titanium retainers reduce valve train mass, allowing the engine to rev higher and faster with improved reliability.

Finding the item was great. There were not many places that had it due to stock shortages from Onan/Cummins. The price was a lot lower than the closest company that stocked it. Ordering was easy. However, I contacted CS due to the fact that the "Tracking" link in the email did not lead me to any type of tracking. The only thing it did was go to the invoice for the order. I was kind of bugged as I was getting ready to head out of town and needed the part. I do web app design and implementation for a living. Someone needs to check the click on links to ensure they go to the proper place.

Quick and easy accessibility for orders
