VALVE COLLET TRIPLE GROOVE (ONE HALF ONLY)

Collet for the 3 groove valve. Sold per half and 2 required per valve.

These cotters go with AHU1897 top cap. On Turbo heads these were fitted on the inlet only.
All early 850/997/998/1098cc heads used the 2A11 cotters, noted by the wide slot in the valve. 
After this later production and most aftermarket valves, used the 88G549EVO cotters with a single narrow groove.

Order the correct cotters to go with the valves you will be using.
