Question on spark plugs...

[ke4peo]

Hey all, just probably a stupid question here.

My 95 Grand Cherokee is in serious need of a tune up. I'm planning on replacing plugs and wires. But I noticed the spark plugs in it are the 4-prong type plugs.

Are these special plugs I have to order from Jeep? Or can I just put in some regular single element plugs (like Bosch Platinum, Autolite, Champion)? I don't want to ruin it or kill the awesome gas mileage I'm getting (about 420 to a tank).

Thanks

Your engine doesn't require special plugs, I'd just run some Champion truck plugs for your application.
