Thumbs up

just unplug the wires carefully and get a sochet that fits the plugs take out going counter clockwise and reinstall. done.
the biggest pain is the plug wire boots they are a biatch to get off, good luck it shouldnt take ya long to do at all.

Get a good torque wrench, too. It's very important to not over-torque the new plugs.

Bratmantlz is right. Getting those spark plug wire boots off is a biatch!!! I pulled two of the electrodes right out of the boot when I did mine. I had to use a pair of pliers to get the electrode off of the spark plug. I assume the dealership that did my 30k mile service didn't use any dialectric grease. The rest was REALLY easy. So, be prepared to go to the dealership and buy an ignition wire or two, and use a bit of dialectric grease on the plug boot to prevent a stuck electrode the next time around.

also remember it is alluminum so you want to wait till the engine has cooled down before you take out the plugs or you will warp the head.

Just in case you missed this while reading the directions from AZScooby, ALWAYS tighten the new plugs by hand first, and be VERY cafeful!!! Careless use of a rachet and a crossed thread and you will have a VERY FUN day!!!
