That all depends on what engine you have. The I4 plugs are relatively
simple to change. You'll need to remove the valve cover and then
unscrew each plug. Replace each with the appropriate plug according
to your owners manual (not all spark plugs are the same, they come in
different shapes and heat ranges). If you don't have a torque wrench
then tighten each plug by hand and then tighten them an additional 3/8
of a turn with a wrench. Make sure you don't mix up the plug wires
when reinstalling them.
If you have the V6 you'll need to remove the intake pipe, throttle
body, and upper intake manifold, as well as valve covers. I'd
recommend taking it to a shop to have the plugs replaced unless you've
spent quite a bit of time under the hood.
