E-3 spark plugs.
 
I would like to replace the plugs in my 2000 wrangler 4.0L. Does anyone have any feed back on the E3 spark plugs? I've heard nothing but good things about them. ???? Are they worth it?

I just went to the dealership and got NGK's. Some of the older TJ's had champions. Several threads on here about autolite plugs. Gap is 35 no matter what brand, make sure and check them. Mine ranged from 30-45 and were from the dealer. Just use OEM and change every 30-40 thousand and you'll be fine.

I put in the iridiums by champion.. I did notice a slight difference.

I use the autolite iridiumd and noticed a difference. Runs another and fuel economy went up, I'm getting 17 mixed 80/20 city/highway mix not sure of highway yet but I'm betting around 22

X2 on the Champs, my TJ is an 2001. First thing I did was change them when I got my jeep last summer.

I think some brands of vehicles are picky, and I believe wranglers are. THO I did use E3's for a 2000 Mazda b3000 pickup before I sold it a few months later, didnt notice anything wrong and some fuel efficiency but not much.
