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.
