Hey everyone, I’ve got a 2014 Jeep Grand Cherokee that’s been a bit sluggish lately. I’m thinking it might be the spark plugs. Does anyone know the proper gap for the 5.7L HEMI?

I’ve had the same issue with my 2014 Grand Cherokee, and it turned out to be the spark plugs. For the 5.7L HEMI, the recommended spark plug gap is 0.043 inches. If you haven’t changed them in a while, it might be worth checking the gap and possibly replacing the plugs if they’re worn. It made a noticeable difference in my Jeep’s performance after I swapped mine out. Good luck, and hopefully, that solves the sluggishness!
