Hi lads, what plugs should I buy for a 02 wrx? Car has a Prodrive pack fitted, walbro pump, cat back and an sti up pipe. Would ngk pfr 7b be a right buy? Tia.
 
I?m completely stock bar a Tomei catback and I got PFR7. I see no reason why they would be bad for your setup.
 
Yup daz' rite :icon_grin: I put pfr6b in mine just because it's not really modded much and they were cheaper ha.
 
Good call. I went with 7's even though it is stock, no issues. Fitting them is grand, not as straightforward as an in line 4, but not as bad as I was expecting :)
