Thanks for the information.
I just completed my fist air filter and spark plug change.
It was a little tough to get that number 4 plug out, but using a ratchet wrench made it fairly easy. Changing the air element was a piece of cake, getting the air box reinstalled was probably the most difficult thing, but it really wasn't that bad. I used fuel hose pliers to get the hose on and right angle pliers to get the clamp back on.
The manual calls for the stick coil bolts and the spark plugs to be torqued, but that wasn't going to happen, at least with my torque wrench. I was able to put the torque wrench on the first plug, so I had an idea how tight they should be, so I did the rest by hand. The stick coil bolts are also suppose to be loctite, and it looked like on mine it was the blue loctite, but I wussied out and use low strength red instead. I did not want any problems when I have to remove them next time.
All in all an easy job, I am retired and slow, so I did this over a couple of days, but if I was to stay on it, it probably would have taken be an hour to two hours to do.
