VAG HIGH BOOST hardened valve keeps

Specially hardened valve keys, ideal for high boost pressures. Suitable for nearly all VAG engines, e.g. 1.8 T, TFSI and TSI.

When installing a new three-groove valves, e.g. Ferrea Valves, we always replace with new valve keepers to ensure proper tolerance in valve retention. 

Price is for a set to match 16 Valves
