Where are the spark plugs on a 99 jeep grand cherokee?

4.0 v6 engine. i know to change spark plugs, used to do it on all my other cars, but i cannot find where my plugs are in this car! i'm at 94k miles and about to take a rather long road trip, so figured it was time to change the plugs. any help is appreciated! thanks!

Ok, pretty sure that your engine runs individual coil-packs... so you wont be chasing leads from a distributor!

Basically, look at the middle of each cylinder head, and you should find a cover that unbolts/unscrews. Under these you should find the coil-packs, and you will need to remove them as they sit directly on top of the spark plugs.

Having said that, is it definately a V6, not an Inline? If it is inline, then you will find them on the drivers side of the cylinder head.
