How do I replace the spark plugs in a 2003 Ford Explorer Limited (4.6L V8) and should I replace the coils at the same time?

There is 9/32 screw that holds the coil in place. Remove the coil and there is a boot that looks like a spark plug wire end. You can buy those from auto parts store, I would replace those along with plugs.You can remove the plugs with plug socket and extension I hope this helps leave cooment

Hello. Since you did not indicate the total miles on the vehicle I can not speak to the coils. Just replace the spark plugs. There are eight of them and then are located at the end of each of the spark plug wires on the topside of the engine under the hood. Joe
