I have been curious on the these spark plugs and wanted to see if anyone here has checked them out yet on there rig or elsewhere ? I'm a little funny about non-gapping plugs that you just drop in. They are supposed to give a better spark and gas mileage. Less unburned gas ?

I saw the guys on horsepower TV on Spike saying they get a cleaner burn, more horsepower AND less emsissions coming out of the tailpipe. Almost sounds too good to be true. Anyone bought and installed these yet?

I run them in my lawnmower and weedeater...they are a lot easier to start and seem to run better. i may try them in the JK

Curious how they will perform. I just bought a set of plugs yesterday and intended to get these, but the guys at the counter advised against these...said they've had quite a few sets returned in the past few months on all sorts of vehicles. Said they were running rough, acting weird, and just causing unusual stuff. I went with Plat II's instead.

Ive got em in my JK. I havent seen any noticable mileage improvement but it definately seems to have better throttle response and also runs much smoother.

Do you by chance have a part # for them and what did you pay for them and where did you get them cuz quadratec did not have them in their catalog and the guy I spoke to on the phone hung up on me

I looked these up online at kragen/oriley and they have the part number listed as E366 but someone might want to verify this. They were listed at $6 a piece.

Thanks I am going to look this up tomorrow.

e3sparkplugs.com lists them as E3.66 .
