Lightweight lifter for all VW/Audi hydraulic lifter applications including 2-valve and 4-valve (NOT 5-valve) including 4, 5 and 6cyl applications. Also fits 12v VR6.
Approx 35% lighter than stock valve, helps prevent valve float at higher RPM and better efficiency.
We've had good results running these to 8300 rpm using our HD valve spring sets.
Weight is 2.25 ounces, stock lifter is 3 ounces.
