I did mine today as well. I removed the battery, airbox, and the secondary air assist pump housing. I did everything from above, except for disconnecting the coil pack plugs and the rear hose clamp on the air assist housing. The bolts on 3 of my coil packs were finger tight from the factory. The 180* rotation while removing suggestion worked perfectly. Driver's side plug removal was easy. New plugs went in just as easy with anti- seize applied. The passenger side was harder. Actually, just the passenger side rear. Had to take a break before I finally got that one in. Reinstalled the airbox, air assist pump body, battery and lower engine cover. Car fired right up! Job took me 3.5 hrs. I'm handy with tools, but am no pro. Car now idles more smoothly, reminds me of when it was new. Pictures are of the pass rear plug cavity, and plug close ups. Bad lighting, all of the plugs looked good with the typical white-ish color indicating a clean burn. Thanks to BoxerGT 2.5 for a great write up and to everyone else for their additional suggestions.
