hi newbie here
ive an 03 blobeye sti type uk minor mods (cat back and panel filter). just wonderin what type plugs are best to run it on? any anwers appreciated

 

NGK PFR7b

 

My remapped 03STi runs fine on standard PFR6B and Scoobyclinic have recommended I stick with these. I have seen posts on his forum where people have experienced some misfires with 7s on on standard/modestly tuned engines, TBH I don't know why.

 

Cheers lads thanks for the help
