what spark plugs and leads are the best to use in my cossie? its gonna be around the 420bhp mark

speak to your mapper and see what he advises for plugs .........he will be the best one for advise..............probably c57's or 071c's as they seem to be flavour of the moment


as for leadsi use magnecors (the thick ones and they have been fine now for 10,000 miles some people recomend std ones........! i think its more personnal choice

but i chose the magnecors as they are a good brand and had had people tell me they have had no probs with em

 

chears mate,just read a similar topic,looks like its gonna be the 071's for the plugs,and i'll take your word for it on the leads

Genuine Ford BERU leads

If they are good enough for 700bhp then yours will be fine

NGK 9's for the plugs

 

yeah,fair comment
