I just finished mine an hour ago!
Three tips I would suggest after just finishing...
1) To make it easier to get to the forward coil pack, that's deep into the car, remove the o2 sensor wire hanger. That will allow much easier access to the hard to reach coil and its only one simple bolt to remove.
2) My 1" T-plug I bought (from Farm and Fleet by the trolling motor/fishing section) was not grabbing that well... So I cut up a heavy dish washing rubber glove and wrapped a strip of it around the plug so it was a bit tighter to begin with. I wasn't getting enough grab out of it.
3) When pulling the T-plug out I found (by accident) pulling on a slight angle it had better bite/grip. I was cautious though as to not break the tube.
I greased the new tubes and they went in without a problem
I had 3 of them that were leaking pretty bad... I had lots of oil dripping on the cat and burning... And all over the bottom of the engine. Had I known how easy it was I would have done this long ago
