Are you handy under the hood? Maybe you can get a friend to help you? The coil pack, shows to be on backside of engine, firewall side, up high. Follow the spark plug wires to the spark plugs. Pull spark plug wire loose, wear safety glasses, use air to blow junk out of spark plug well. Use spark plug socket, extensions--rachet, whatever tools you need, to get spark plugs out. Your local autostore should be able to help with tools. With some of the plugs, you may need to remove air-duct, whatever, to get the plugs out. As far as the backside of your engine, I'd have to look at it.
If you don't understand anything I'm saying, you need to get somebody to help you.
