Oem. You may never know what another spark plug might do to our engine. It could ruin it. So I'd just go with OEM ones.

Stay with OEM's. All Mopar engines seems to go coo coo for cocoa puffs when aftermarket ones are installed. Thats not the case all the time, but most of the time it is.

Irf, How many miles you have? You may not need it. Also, It could be included on the service warranty.

I forget it this was answered already or not, but do you have to go to the dealership to buy these or can they be purchased at say, autozone?

do you know what brand plugs the stockers are? The last plugs zI bought from a dealer were only like $1.69 each or something....

I will give them a call tomorrow and get a price check then, shouldn't be too bad at all. I know they're gonna try and convince me to let them do it and charge my ass off.. lol yeah right!

the plugs are easy.....one bolt holding the coil on and you have access to the plug

Mopar OEM P/N SPZFR6F11G MSRP $3.70 each

NGK: ZFR6F-11G

You can shop around for the NGK's, but online + shipping you might not end up being too much cheaper than the Jeep dealer. Not sure if Autozone carries them.
