These valves of head size 1.220" / 31.00mm have been made from top grade performance material only for MINISPLUS .
They are light, strong, coated black for longer life.
The length is 3.570" / 90.93mm the same as MK11 Cooper S and has several advantages in performance or race applications.
These new valves have been designed in conjunction with our own Australian performance GURU...Graham Russell and the head size is very suitable at 1.220" and whilst smaller than some UK valves gives very impressive power and torque in the region of 150bhp from 1300cc.
