These blanking plugs allow you to remove the dizzy and plug the hole in the block they leave behind. Designed for the A-series and A+ series engines these aluminium distributor blanking plugs come complete with O-ring ensuring a tight seal.
With 27mm and 34.8mm diameters these plugs can be used to plug the distributor holes of a number of other engines. The Ford Crossflow in particular can use the 27mm (A+) blanking plug
Unsure of which type you need for your engine? If you look at the fixing for the distributor and the distributor is held in with a separate bracket, secured by a 3/8" UNF bolt, then you need the A+ bung, however if it has a 1/4" diameter bolt through a hole (at about 2 o'clock - the distributor being the centre of the clock) then you need an A series blanking plug.
It is essential that once the distributor is taken out that the distributor drive shaft and sleeve (A/A+ series only) is also removed as failure to do so may result in damage to your engine.
