do them one at a time...PLEASE!!!! don't try to be cool and take them apart all at once, you might mess up the order.

on another note advanced auto parts sell this "kit" that has the tune up tools for about 8 dollars. it comes with the big wrench, two extensions, a swivel head, and then 3 different size "spark plug" heads for you to do your spark plugs. i got that, and it's awesome. i think it's by mech-power. it's great if you don't have the tools!
