VAG High Boost Hardened valve wedges BAR-TEK®

Specially hardened valve keys, ideal for high boost pressures. Suitable for almost all VAG engines, such as e. g. TFSI and TSI. When installing a new three groove valve, such as e. g. Ferrea valves, we always recommend installing new valve keys. This ensures that the valve is properly seated. If used wedges are used, they may be worn, the valve will not seat correctly and will have play. This can result in valves that do not close properly or even engine damage. Price for 16 pairs, for 16 valves.
