Porsche 964 Twin Distributor Drive Belt Motorsport Cooling Kit for the twin distributors fitted to All the Porsche 964 none Turbo models manufactured between 1989 - 1994.This Motorsport distributor drive belt cooling kit was developed to draw cool air into the distributor & onto the drive belt, to prevent it from over heating, greatly reducing the lifespan of the belt, leading to belt failure - leaving the car to run on just x1 distributor which will only fire x1 of the spark plugs in the twin plug heads. You then run the risk of a holed piston (at your peril & great expense!).Fitting this cooling kit will minimise the risk of drive belt failureOur Ref No - Box 208
