Eurocode Tuning, through our 15+ year partnership with Ferrea Racing, are proud to release the ultimate valvetrain upgrade for the 2.5T EA855 DAZA/DNWA cylinder head. Ferrea Super Alloy engine valves represent the highest level of sophistication in valve technology. These valves are designed to handle the extreme heat requirements and punishment of modern high boost, turbocharged engines.
For those who are looking for the added benefit of upgraded valve springs, but do not want to remove the cylinder head Eurocode has the perfect solution for you.
Utilizing just three factory tools (VAS6151A Valve Keeper Tool Kit, VAS5161A/39 Valve Keeper Tool Kit-Guide Plate 2.5L TFSI and a Cylinder Leakage Tester to pressurize the chamber) you can remove the OEM springs and replace with our upgraded Ferrea Valve Spring Kit without removing the cylinder head.
