Stock plugs or new with smaller gap

[Schroedes]

Gentlemen, my 2021 has 2500 miles on it now. Engine Mods are intake and catback at this point with more in the future.. I've looked through the forums and what I'm wondering is if I should change plugs to smaller gap or not with my limited mods?? Any benefit to doing it? I have access to 93 octane here in MN. Thanks

Obviously with JB4 it is recommended to change plugs. No matter what, if I were going through the hassle of changing plugs I would spend the 60-120 and regap new plugs.

With my current setup is there any benefit to changing plugs?

Nope. You can leave them like that.

To answer your question, going for a smaller gap is only useful if you have added power. This makes it so that your spark doesn't blow out with the increased pressure in the combustion chamber. If you don't have any significant added power, you don't need to run a smaller gap.
Hope this helps!
