Please son't yell.

I really hate to do this. I have searched the database and have not found anything relavent to this.

I was discussing spark plugs with the mechanic friend of mine who lives next door to me. Long story short he suggested looking int the E3 brand of plug. Besides it's claims of higher this and that, it does have a copper core. Also a nickle electrode. I am not sure of the conductivity of nickle.

Do any of you have experience with the E3?

Personally the E3s are mostly hype, stay with what works

The OEM NGK's work good. Autolite double platinum works good in the KJ.

Nickle is a great conductor. NGK or autolite are proven choices. Heck be bold give the E3's a whorle .

Dont know of any professional mechanics as of yet that think the E3s are anything more then splitfire hype. What matters most is the correct gap for the amount of KV that is being delivered thru the plug vs the internal swirl and turbulence inside the cylinder. You want the max KV to jump across as big of gap as it can reliably support under those conditions. Those pretty designer electrodes will have no improvement on that. Platinum tipped plugs are used solely for wear resistance, while Ive been told by trade sources the copper plugs deliver a hotter spark, and therefore performs better. On the older ignition systems, things that did help was things like MSD ignition modules tied to one of their coils. Those and other brands would step up the voltage going to the ignition coil, then the coil boosted that alot higher. With that, you could run bigger gaps, exposing more of the spark to the cylinder and getting more reliable spark. You cant do that anymore, so your best bet is to stick with what the OE designed to work in it.

Yeah, that is well put, and clears up the hype on MSD too.
The guy next door may not have the wealth of experience like you, so I can see why he could suggest it. He also has a straight 6 he's been working on rebuilding for about a year now, sitting in his driveway. So perhaps not a great source for info. Thanks again.

e3 spark plugs

After watching too many sunday morning horsepower shows I decided to tweak my '03 Liberty. First up; K&N cold air intake & filter, MagnaFlow cat-back exhaust and e3 plugs - just to see if I would experience anything the guys on the shows suggested I might. Did I? Yessiree, I most certainly did. Quicker exceleration and better gas mileage. My rear end suggests I'm getting 20% better performance. My gas mileage (this time of year) went from 18 mpg to 21 mpg and once (that I remember) to 22 mpg. Everyone has an opinion and I'm just sharing mine. I've come to believe that OEM is just hype. A lot of people turn their noses up at "after market" parts. There's a lot of good innovative after market stuff out there!

There is some good aftermarket stuff, then there is alot of junk. 20 years ago, you could go to a parts store and buy decent parts, now, its mostly chinese cloned garbage. If I want a thermostat to work reliably, and at the designed temp, the first time, I almost have to go to the dealer. O2 sensors? Forget the bosch junk. Trust me when I say, I would use more aftermarket stuff if I wasnt having to warranty so much of it to get a part that worked. Your K&N is probably the one single device that made a fuel mileage increase. Lots of people have opinions on them and I'll share my experience. Every, and I repeat, every reuseable filter'd vehicle that comes in, has a nice layer of dust and dirt... on the inside of the intake tubing going to the engine. They typically have the dirtiest throttlebodies, and have the highest incidents of mass air sensor failures, despite what K&N says. That evidence shows, its allowing more dirt and air into the engine. Ill take the paper filters any day.

Well daddyo, ours get's better milage without all the stuff you added!
And it has 235,344.1 Km/146,236 Miles on the clock...
Oh, and a lift, bigger tires...
