I know theres a bunch of these threads out there but they're mostly old posts. Wanted to get a feel for what y'all thought were the best spark plugs and cables available on the market right for JK's. I need to swap mine out this weekend so want to see if I can get some ASAP. Thanks!
 
I'm running Performance Distributors Screamin Demon coil and their Live wires with platinum plugs on my 2010 - definite improvement over stock
 
both, the responsiveness and idle are smooth, the mileage even with superchips 90 tune is much better when I'm not driving a maniac.

my best mileage hand calculated was on regular trip to Utah, always the same route - just over 19 mpg @ 65 cruise control all the way - even when posted was 75, weather was perfect no additional headwind!

my setup 2010 auto, superchips 90 tune, 35's. 4.88's, screamin demon w/ livewires, dynomax vt and cruise control! usually on the freeways I average 15-18 depends on foot and headwind, around town about 13-17 depends on how lucky i get with the green lights :thumb:

I should mention I got the demon coil setup when I installed my lift and tires - this was before superchips, gears and muffler - it made a difference and with each mod more improvement to get what power the 3.8 has out of it.

anyone with the E3's I've read some reports that they fowl out prematurely

From what I have gathered, the E3 are no good for JKs... I'm thinking between the bosch +4 Platinum or the NGK Iridium Ix. Most people seem to be running the Omni-Spark or the Granatelli wires. I need to get them today so I can install them this weekend. Hopefully I can make up my mind soon.

That's good to know , I was thinking of trying the e3 just to test them for myself but I hadn't read anything that said they weren't good for jk's.

I mean, probably ready about 4-5 posts out there saying to stay away, that's good enough for me. LOL
