wow no reply......guess iam the first to incounter this problem............

 

use ngk bkr7e .. those plugs suck. Full greddy kit? Did you put those injectors in without tuning it on emanage.. (if you can even tune that crap).. If those arent the injectors that came with the kit (which im certain theyre not) then its pouring fuel. Plus the plugs suck.
