The previous answer was left by a no talent, unhelpful, ass clown.
If you are use to working on vehicles from the 60's through 90's, then I can understand your question. They are not connected in the traditional manner with large insulated spark plug wires, but more resemble a wiring harness like the one that connects to all of the fuel injectors.
To get to the plugs; remove the oil filler cap so that you can pop off the plastic cover on top of the engine. Then replace the oil cap so that nothing falls into the engine. You will then see three flat black things with electrical connectors on them and a 10mm bolt on the side (the vehicle's right). Remove that bolt and pull the whole assembly out. You will need a spark plug socket and a 6" extension to get the spark plug out of the cavity that it is in. It is the same for the back side of the engine, only a little more difficult to get to. Be sure to lubricate the rubber inside of your spark plug socket or you will have a heck of a time getting your socket back out of the hole after installing your plugs.
By the way, after 100,000 miles, the plugs that I pulled out looked just as good as new ones with only minor carbon build up. I think I will give it another 25,000 to 50,000 before I inspect them again or if the gas mileage drops.

Change the plugs and wires at 100,000 miles unless you experience poor performance or a drop in MPG. In that case change them sooner.
