Hello.

I’m thinking on brisk Primium spark plugs, some people say that they are the best for prepared engines, others told me that I will damage the engine (cylinders) because spark ignition is too strong.

What do you think about it?

Is it true?

best regards

yeah i would like some advice on this too - i have bog standard plugs and cables - whats best for me to buy on my limited budget?

All I can really offer on this one is that I've tried Champion, NGK and Bosch super 4 plugs. The Bosch ones seem to make it run a little smoother but there was nothing different imho with the other ones. Have heard good things about Champion EON2's though.
Plug leads, tried Halfords, Bosch and Magnecor - the magnecor seems to make it a little more responsive at lower speeds / throttles.
Damaging your engine with too strong a spark sounds a little unlikely to me, if not impossible using the standard coils.
