Question Spark Plug Recommendations...?

I own a 02 wrx that I will soon install Borla headers, and catless up and down pipe. I figured I might as well change the spark plugs while I have that much of the motor taken apart. I was going to buy the stock NGK's, but was wondering if there might be a preferred spark plug out there, especially for the increased hp.

Change it Platnum Iridiums.... A step colder isn't a bad way to go. As for the headers... send them back.. your money could be better spent in a number of ways. You won't see the gains your looking for. Search it if you don't believe me, this has been covered time and time again. Best of luck

You are not doing anything that requires a change in spark plug heat range. Stick with the stock heat range.

If you install headers, you will pick up some power on the top end, but you will be giving away torque on the bottom end. More torque = better acceleration.
