How to change spark plugs in a 2008 jeep compass?

You need the correct sized socket, a ratchet, and an extension. Remove the wiring harness connector from the coil caps and pull the coil caps straight up.

how often do i have to change the spark plug on a 2008 jeep compas?

Depends on the type of plug. Most of the newer vehicals (like yours)use a platnum plug that is good for 100,000 miles. (though i have replaced them at 75,000) old standard plugs went from 50 to 70,000 miles. Consult your owners manual in the maintenance interval section to give you a better grasp on it, but be aware that other factors can play their part (bad gas, dirty air,poor maintenance, heavy hauling,ect) in accelerated wear.
