Right i have a stage 3 esc cos and am running the denso plugs which are running fine. I have some 071's which run lumpy at idle, i rang EA and he recommends champions 59 c's i rang SCC they recommend champion 57c's. I dont wish to use the denso anymore as i have heard rumours they aint that great. Someone on here said the 59's will have bad idling and i thought the 57's were for cars with more bhp??????? So why is it running fine with one set and crap on another???

 

i had problems on my 400 bhp engine with c57s,then changed to c59s and it was sooooo much better,dont remember any idle probs.

 

c57s and 071's are both fine

 

071's in mine - 22psi and around 300 bhp - more than impressed by them, and at 12 quid a set, good value too

 

I use c59's, only have a bad idling when engine is cold, disappears when it's getting hot so I'm happy with them. Will try the 071's soon

 

12 quid,,,, STU send me some plugs

i run 57's, and had ngk 9's, but missed at same plug gap.

at my local ford dealer 071's (std esc cos plugs) £49.89 for set, so i rang the 2nd closest ford dealer, and got the same price.
