hi just wondering if any one has fitted NGK BKR7EIX (they are the iridium ones that are one step colder) to their wrx and if so how do they perform as ive just purchased some off ebay for £30, not really sure if ive done right thing buying colder plugs

cars current mods are, free flow panel filter, all cats removed and bailey dump valve and running 15psi boost according to boost gauge i am also planning on getting it remapped soon, but just wondering if these plugs will be ok, before i go and screw them in, cheers.

P.S if they are ok what gap do you set them too, heard lots of different settings just want to make sure i get it right

 

so has anyone fitted these to a wrx

 

Not sure about the ones you've bought, but the usual ones are PFR6b's/7b's (6 std & 7's colder).

However, if the ones you have are listed for your car they should be fine.

 

i think the ones you got are for classic impreza
