Did the job this past saturday and it took 2 solid hours. The only hole that gave me issues was the DS rear, as the coil boot did not want to seat right. Took about 10 tries, but it finally went on right. Also, when I checked the new plugs all the gaps were too small. Had to open up all 4 to the .030 mark. Glad I checked this before putting them in. Thankfully the old plugs did not look too bad for being original with 67,000 miles. Car seems to pull a bit stronger with the new plugs. Very do-able job with the right tools. Best advice is to have several 10mm, 12mm and plug sockets available. By having shortys, deep socket, and standards of all (happened to have a shorter plug wrench that gave me a tad bit of extra clearance for the DS rear) three....your life will be a whole lot easier. Nice thing about this job is it also afforded me the opportunity to clean out the engine bay a bit. Shop vac was able to suck quite a bit of leaves and other crap out of there.
