what plugs is everyone using in their jeep.
i heard to stay with the champions from the factory
others say that those e3 plugs rock

got a 2000 xj classic

let me know what you suggest for better mpg

Diesel

Anything with a .035 gap made for XJ's work.

I like e3 spark plugs

black2000xj

where did you get those e3 plugs and how much were they per plug
did you notice a difference from those e3 in mileage gain or not really?

Metlic53

yes, 1-2 mpg better, ive tried 3 different kinds of plugs and these showed the most results. smoother idle, quicker start, quicker throttle response. They are 6-7 bucks a piece where i am at. they sell them at oreilley, auto zone, advanced auto. i'd call to see if they have them in stock.

Accel

ok sounds good, i will call around to see

as long as they are worth what you paid, that is good

1-2 mpg increase dont sound bad either

From pretty extensive experience with 00-01, I'd recommend NGK.

84-99 : Champion Coppers
00-01 : NGK

ngk plugs? are they better for 00-01 jeeps than those e3, you said you have experience with plugs, i like to hear that, what makes these so good

im open to all opinions

Metlic53

well mine is a 97 and i had better experience with the E3's

black2000xj

well the previous guy said that for pre-1999 was one plug, 00-01 xj's are a different plug, just wonder if those e3's work good in your 97, but maybe not to good in the 2000 like mine

this is the reason i started this thread....different plugs work in different year jeeps

love this xj forum

00-01 = distributorless ignition I believe, that's why the plugs are different.

EjGonzales

The e3's do work i have been rocking with them for about a year now but i own an 89 your is a bit newer so it could be different

black2000xj

yea im looking for something that will improve the mpg on my 2000


im pretty sure i have the factory ones in yet (140,000 miles on them) time to replace them

just want to know what to go with

Metlic53

They make the E3's for your jeep though. They are going to give the same results. buddy of mine with an 00 wrangler has them, i've tested these on 5 different engines, same results. so i doubt it matters if yours is 00 or not.
