Advice from someone who just completed this DIY. (Heads up I didn't read every reply in this forum so some of this might have been addressed already.) I was only able to get one coil off without removing that rubber/plastic seal. My car is AWD, though that shouldn't make a difference in room between the engine and fenders. You do not need to remove the battery tray at the bottom, just the battery. A battery must of leaked once and the bolts on the tray were melted almost. Because my car was AWD the coil under the dip stick was kind hard to undo the bolt because the placement of the dipstick tube.

Sorry to raise up an old thread but I had to Thank the Helpful Folks that contributed to this thread (Especially Road Frog for starting this and Many other Helpful threads)!
I bought the factory plugs from our local Lexus dealership (wanted to avoid fakes and they actually had the best price around after discounting not having to pay for shipping) and did this job in around 2-2.5 hours without taking the battery out. I changed the rubber seals/gaskets/whatever that wrap around the coil too. The old ones were a little brittle and I also figured that I'd probably drop one or two while taking them out (which surprisingly didn't happen) but since I was in there already, it was money well spent.
Thanks again to all the contributors that posted up here. This forum ROCKS!!![Smilie](https://www.clublexus.com/forums/images/smilies/smile.gif)

Not to be smart a$$, but this is a very basic job. If you are "2 Days" in and still can't get them, I would highly recommend taking to a shop. Otherwise, just go out and buy some misc extensions and swivels and try again. This took me maybe 2 hours and that was replacing the coil gaskets etc. Very simple job that some seem to want to make a major ordeal.

It's nice that the plugs come already gapped but I ran a feeler gauge through them anyway and surprisingly enough, they were all spot on the money.
