Has anyone tried these plugs or heard anything about them? I met a auto shop teacher who told me he does extensive work on all jeeps and that he puts these plugs in a 4.0 and can feel the low end power they give you...Tj

I run those. They are pretty nice, though I have never had use of my engine's full potential(fuel pump issues). When my pump wasnt acting up, however, my jeep had great low end torque.

I used to try different brands of plugs on my turbo cars, but wasn't satisfied. I went back to Champions, just playing with the heat range choices to match the engine tune. I always used Champions before that, and I've stuck with them ever since. The "flavor of the month" plugs are a waste of money in my opinion. As long as they make Champions that's what I'll be using in all my vehicles. JMO

Waste of money. NGK's or Autolites are your best bet for replacement plugs. If you want a better plug, iridium plugs are the way to go. Of course there quite a bit more money. I would save your money for better plug wires.

I just removed mt autolite platinum plugs due to one going dead....i was amazed at the increase and how much smoother the jeep felt after puting in some fresh champions. IMO there isnt a Magic plug.

Well, I would just like to add this. HorsepowerTV tested them on their engine dyno, and had a horsepower improvement and a fuel mileage improvement. Now, that's not to say they are perfect for every application, but on their test motor, it worked.

Whoops. I didn't realize they had the clip on the website that I had already looked at. Anyway, it looks like it could be a used one, but also, if you notice the one before it is darker too. Also, even the aluminum the Bosch is screwed into appears darker, so I'm thinking it may just be lighting. I would hope they would not test a new E3 against a used Bosch +4, but E3 is a sponsor of the whole Powerblock group.

Lighting maybe.......little bit of sponsor love

something fun to ponder on anywho
btw the +4's are also pretty good and a few bucks cheaper than the e3's
