hi i was reading on here the other week about what spark plugs to run in an rst s2 some one was saying that people have been using cossie plugs and getting good results is this true if so when i order a set what do i order them for a 2wd cossie anyone know im running a 1.9 stage 3 head collins chip etc can any one help thanks

 

i'd say, go for the 071C's from ford, the proper rst plug that a lot of people use in big power cossies with no problems, im runnin gthem with 1.9 bar boost(peak) and have no missfiresa t 0.9 mm (admitidlt running a coilpack)

but as they are only 12 quid a set, i'd use these

 

thanks dave top fella
