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.
So I installed the flux capacitor but the Jeep just won't do 88 mph.
