Hey guys. I have a 2016 ST1 and am replacing the factory spark plugs with the Denso ITV22 plugs. I’m looking for input on the proper gapping for them. On Steeda (where I purchased them) they recommend .029 -.031, and on Stratified for ST’s, they recommend .025 - .026....Do any of you have experience with these plugs and know the proper gap number? I know they’re very common. Thanks

I wouldn't swap plugs until you are ready to tune the car. Stock plugs are fine.
