Thanks for the response...[my opinion]People buy them and claim gains. My personal opinion is it's hog wash. Today's factory ignition systems are very stout. It is not the day of points or cheap factory ignition boxes anymore. I installed an MSD 6a box on my 1972 Plymouth 'Cuda (factory ignition) and hardly noticed a difference. Therefore I have no hope for upgrading the factory JK stuff. If I had a problem with the wires or coil, I'd consider it. But I wouldn't replace a functioning ignition with it. MAYBE if I had a supercharger to help the spark out with the added turbulence and fuel in the cylinder...thats about it..[/my opinion]
Again, it's certainly up to you. Whatever you do, do-not buy E3 spark plugs. My preference is NGKs, never let me down (like the E3's did 300 miles from home)Well I got some bad plugs, was actually looking @ the wires as a replacement while fixing bad plugs and was thinking added heat protection because of Texas heat.
Yessir, Plats are generally a super long lasting plug. (100,000+), which I think is the factory plug in the JK. I prefer to run the cheaper (but still really good) Iridium plug, but change them more often.Iridiums are cheaper than the laser platinum
Never had the E3's in the Jeep, but have heard only negative about them. I did put E3's in my daily driver ('05 Kia Spectra) and will be removing them this coming weekend. I have given them a full 15k miles and they SUCK. Hard starts, idle stumbling, accelleration stumbling, reduced fuel milage, you name it.What happened with the E3s?
good luck with them, I personally know 3 people including myself that had misfires with them in their jk's besides all the people I've seen online here post same problemI would use them again. In fact pretty soon I'm going to put a set in my JK.
I had the E3's, they were great....HOWEVER... didn't last, mis fire codes and the rest people have heard. Changed them out after 15-20K.
Misfires are the big problem in the jk with E3's :shaking:. Maybe it's just something about the jk not liking them. I have yet to see anyone claim they are trouble free in a jk yet.I had the E3's... 2 miss fired after 200 kms of driving... long drive home that night. I returned them to the company I got them picked up some stock ones. E3 found out and sent me a new set. Anyone one want them just pay the shipping.
