I've searched as much as I could about this topic and have some concerns, questions. I'm putting on my Code-3 Pulley and LET tune this coming weekend and is it imperative that I change the plugs to a colder one? I know some SRT-4 folks that just regap their plugs to compensate for the extra power and why can't we?

Are there folks on here not changing their plugs at all with their upgrades and what are the drawbacks? I want to be sure that the car is running optimal without any glitches. Also what spark plug options do we have besides the 1-colder BKR7EIX-11? Also if the stock gap is 40, what should it be changed to?

So please post up what you have done if anything when it comes to the spark plugs.

I'd like to hear from the folks that haven't changed their plugs at all with their upgrades. Thanks!
