1 Step Colder Plugs -Retune/change plugs?

[sdoo500]

Probably a dumb question but looking for a little advice. Sold my paxton kit and returning car back to stockish (off road x, axle backs, Lund tune)

I have one step colder brisk plugs in the car now from paxton. Do I need to have the car retuned if I leave these in once the car is back to just bolt ons? I can just swap plugs back to stock too rather than getting a retune as I'm sure there isn't much benefit to colder plugs on a basically stock car.

I have heard of 1 step colder plugs being recommended even for regular spirited driving and not just going to work and back. Should be fine to keep running em. On your particular car and with your particular driving habits, you would probably want to give the plugs some more run time and then remove and 'read' the spark plugs to really know for sure.

Won't hurt anything. I run a colder plug than what I was tuned on. It idles rougher but drives just fine.
