A neighbor of mine installed Bosch +4 Plugs and he actually gets better gas. I have the +2's and I can feel a difference in acceleration. But everyone has there own opinion.

Don't buy any hyped up plugs. I don't believe they are worth the extra money. I just don't see how they can perform any better. After all, a spark is a spark no matter what. In the presence of gasoline and oxygen, anything will ignite it. As for a hot or cold plug....i no nothing about.

I doubt it man.

The engineers of your truck knew a thing or two, go OEM.

I do not trust that the manufacturers have accommodated for the extra mass with these cross, split fires, 2 grounds, and 4 grounds plugs. The heat range is the most important property of a plug. The heat range must be maintained in order to avoid pinging and incomplete combustion. I will always use a traditional style spark plug. Oh yea, if any of them claim to increase hp or mileage, then this is sign. Stay away.

While the Accel coil and plug wires aren't junk by any means, they aren't going to do anything to increase horsepower. Neither is any particular spark plug. The best you can hope for is to help your ignition system operate more efficiently, which may translate to better fuel mileage. In my experience, NGK makes a quality spark plug that holds up well and operates as efficiently as any.

I recently changed my plugs thinking it might have something to do with an idle problem I had.

I had NGks in there and changed to those champion truck plugs Ive heard people mentioning on here and my MPG dropped 3-5mpg.

I plan on putting some NGKs back in there asap.

I agree with Matt. I just put in the +2s and I've definately noticed a performance different. Fuel economy, i haven't noticed a change.

A higher quality plug gives a greater spark igniting more fuel, faster. That doesn't mean you're sacrificing relaibility either.

Sure, the Jeep engineers know a thing or two, but they're also being directed by Jeep executives. And Jeep, just like ANY other car manufacturer, wants to save money.

If Jeeps came from the factory with top quality spark plugs, air intakes, injectors, exaust systems... etc... the thing would cost a lot more, and may affect sales.


Grandman, go for whatever suits your fancy, but I do recomment the Bosch Platinum 2s.

NGK`s are a really good plug. I put in the bosch + 2 plugs (platinum) and they seem to do the trick.

I may be a newb to the jeep thing...but I know a thing or two about spark. I have a 1977 goldwing that has been highly modified. One of the best things that I did to it was replace the entire ignition system. I did it a component at a time just to see the difference. When I replaced the coils with accel supercoils.....the idle on my bike jumped 300rpm on the next crank. My plugs burned cleaner and lasted longer. Throttle response was better and milage went up. There is something to be said for getting a clean burn from tons of voltage. Good wires gave me a boost as well. Changes in the plugs gave me the least amount of help....in fact stock ngks at the recommended gap were best. Splitfires have been known to catastophically fail in the engine....I've actually seen this and would not risk running small pieces of metal in my engine.
