silverglanza Posted November 28, 2009 Posted November 28, 2009 hi guys i just ordered some magnacores and some iridion 7 plugs i ordered them as my car seems to be stuttering going up the rev range not to much just a lil bit do you think they will sort it some help would be greatfull as hell Quote
GT Phayer Posted November 28, 2009 Posted November 28, 2009 yer could do mate if a ht lead is breaking down it causes a juddering affect when drivin not all the time though hope this helps just check the plugs for wear on the electrode and cracks on the white bit mate Quote
Steve GT Posted November 28, 2009 Posted November 28, 2009 even if it doesnt help it mate its a damm good upgrade trust me very good spark with iridiums and magnecoresplus if you ever want to up boost or hybrid it these mods will support it wellso good decision in buying them no matter what the outcome Quote
