I took in my car to the dealership for some work and one of the problems was that the car needs new spark plugs. They wanted to charge me like one hundred dollars to replace the spark plugs which I thought was ridiculous. So I figured I would buy my own spark plugs and replace them myself, I figured it would take me fifteen minutes. Then I opened the hood and these new cars are crazy, I don't even know where to begin. There is a lot of stuff over the spark plugs and including a medal cylinder and lots of electrical. It sure does not look like your normal spark plug set up. How do I complete this task? Is it possible for me to do it or am I going to have to take the car in to the dealer?

Remove the coil housing from the top of the engine, then remove the spark plugs. Use only AC Delco spark plugs. Here is a video to help you
