Spark plug Q
Hi all,
What is the best spark plug to fit on a fairly standard WRX? I have a 96 WRX with full de-cat, Induction kit and a Polar performance chip (this ups the boost to 16psi or thereabouts)
I know that PFR6B is for a standard car and PFR7B is for a modified car but will putting PFR7Bs in my car be worthwhile or just stick to PFR6B?
Thanks

Just fit the 7's.
They have no adverse effects, and if you decide to up the boost, or tune the car a bit more you won't have to swap them out again.
