E3 spark Plugs

Been hearing about these plugs and how great they are to boost HP and MPG, anyone try them yet?

the design is horrible with great marketing if anything the electrode hide the spark from the mixture and does not/help give a complete burn. Better to index spark plugs than anything vs those expensive things.

A search on this topic will turn up a lot here. Most negative.

Its an 08 Wrangler 3.8, 6 spd man. Lifted on 33x12.50 with 3.21 gears. I love it. Its geared Hi but put it in four wheel drive and it crawls. It was already equip. With an Air Raid air filter system. My first Jeep and having a ball with it but at 3.29 a gallon it would be nice for more MPG .

You could put the stock 32's back on?
My banks seems to be getting me a wee bit better mileage you all set with the Air Raid but--

Best advice.. REGEAR

Speaking of Plugs, when do most change their plugs and what plugs do you use?

Good question, read threw some other forums and from what I've read--the factory plugs are good for 100k.
Some change every 30k for kicks and found gapping issues. I have 38 k now and debating changing the plugs. Why not? I figure it's inexpensive and I can look at them and check the gaps. I do have some stumble at idle so will see.

Afraid to tackle that rear plug. I read it's a real PIA.

I can tell you my plugs were absolute crap from the dealer. I pulled them to inspect at 3k miles and they looked like they had 150k on them, most were no where even close to the same gap. I put E3s in mine and haven't looked back in 14k+ miles. Yes, they are more expensive, but I like them, they make my idle smooth, like a brand new vehicle should be. Works good with intake/exhaust too.
No negativity here and I actually run them in my rig. Am I a scientist? Not exactly, but I did stay at a Holiday Inn last night.

I have a new set of plugs waiting to go in, but I've been procrastinating. So much so that I thought it was better to power wash my siding this past Saturday. I plan on putting in new wires at the same time and routing some of them behind the engine doesn't look like much fun either.

Seen mention of going up through the wheel well with extensions. Still looks tough to get to though.

Ehh the rear plug on the passenger side is not really all that hard. You could go through the wheel well, but I did all mine from the top with absolutely no problem. Took me about 30 minutes total. And I found the plugs if yall want pics of how mine looked. And yes, the wires routed behind the engine does look like a challenge.

If you put in any good brand spark plug that is made for the jeep will smooth out any idle and etc. NGK's and Denso are what I'm referring to. More so with NGK's

Here are my factory plugs, well 5 at least. Champion re14pl. Gap is all over and they look like shit.
You probably cant see but the electrodes are rounded pretty bad. Runs much better with e3s. Course anything after this would probably run better.

Look hit what was the mileage?

I have heard of gapping issues but I believe it was on earlier JK's (like mine)

This is on a 2010 the plugs have, now that I look at the receipt, around 2800 miles. Mostly highway. I have 18k on in 6 months. I drive a lot of highway miles.

I've dyno e3's and actually lost power vs running other plugs, but from my experience the only good thing about champions are their on piece design. You are right any spark plug that replaces those will sure as hell do a better job!! lol
