The video speaks to the concept, for a different vehicle. It is very close to what I had to do on a Chevrolet venture van. http://www.youtube.com/watch?v=C-LCcAmhiHE

Change the oild more often, but you will need to rebuild the engine.

NGK won't let you down.

You will need a 5/8" spark plug socket. You will definatly want some 3" and 6" locking extensions so you can get it back out of the hole. You will also want some good long needle nose pliers (8" or more) to twist and pull on the plug wire to get them loos without breaking them.You take the 4 screws loose from the plastic cover on the top of the engine, pull the air duct-work loose. On some models you want to take the power steering reservoir loose for more room to work (and the brackets that hold it).From there it is a matter of figuring out how to sneak in and get to work around all the junk.
