Do they fit on any cossie loom? Or do they have a completly different one?
If there that good why do they need changing after 300bhp.

I need to know as I have one at hand but is it any good for my application.
Do they run a coil pack anti lag etc?

I'm running low comps
greys
gt35
reprofiled kent cams and verniers

So should be well over 400bhp...
