I installed six of those Ripp coils some time ago because of the claimed +20ish pound/feet torque increase.
I recall seeing about nothing concerning performance increases, except perhaps a placebo effect.
Immediately afterward I headed off on a four-wheeling adventure in North Carolina. While motoring around on the Blue Ridge Parkway, the engine would often stumble, and I feared the thing might stall. Later on, it cleared up and I then drove out to New Mexico and Colorado from Kentucky to wheel mostly in the San Juan mountains.
We had the same occasional stumble there as well, and I think I just came to believe that was normal for my JT.
Well, over the months afterward up to now I would get a good stumble here and there right up until a moment on the freeway, today when one coil quit.
I managed to limp home on five of the six cylinders and did a workup with code readers. I had a historical P0303, and several recent P0303 codes, Misfire in cylinder three.
Yep, bad coil!
So the stockers are going back in, and BTW, I really don't use my jeep for much other than adventures and it has low mileage less than 18,000 miles. I think the coils went in somewhere around 2K miles so the Ripp coils lasted around 16,000 miles.
