Group a by definition has to be used on some oe cars.
The group a coils are well worth the money, without a shadow of a doubt the best £40 odd I have ever spent for the benefits.
It was not designed for fords but was in fact an OE part on LANCIA's .
At the price it is not expensive, but the difference in performance with one is immense, this is good and bad!!
Good for the benefits, but bad as it shows what a pile of crap ford put on there in the first place coil wise.
Even a boggo car benefits greatly from one.
