I personally only used Bosch Platinums in all three of my Grand Cherokees with the 4.0 I6 and both Wranglers with the same engine. They gave great performance and 1.5-2 mpg's better than the stock plugs in every one of them. Tried them in my current Grand Cherokee Overland with the 4.7 H.O. and they perform well there too (not the same gains as in the 4.0, but no problems. But I, like many others, have had issues (unsteady idle, lower mpg's) with them in my Hemi...

 

i agree wit hammer, i bought the new ones bosch came out with, they are bimetel? 1/2 copper diode and 1/2 platinum like i said its workin great seems a little pepier and smoother

That didnt work worth a crap either! screw it, Ill try again tomorrow!

 

I used the Bosh Platinum in our 04 2500 and loved them so much I took them out before I traded it in. It is worth it to me NOT to have to change them every 30k. I also heard the problems are with the double and quad platinums not the single regular looking plugs. Get yourself a piece of hose to fit over the ceramic to make the back ones easier to install. I actually sat in the engine comp with feet down by the PSpump to do the drivers side. You WILL need a swivel.

 

I can change mine at the track between runs, about20 minutes, and dont use the swivel socket. Where are you guys using a swivel? which plug?

 

i had to use it in the rear (taken out of context, that could sound a little queer) to get around the brake booster on the driver side...and, crap, something on the passenger side, can't remember now....something with the A/C maybe
