2007 RX350 Coil Replacement bracket question
I'm about to change (hopefully) the rear coil pack on my 2007 RX350. Started throwing a P0355 at only 75000 miles, read several posts here and not looking forward to task. The one stumbling block seems to be the bracket commonly referred to as the Surge Tank Stay - the one most difficult to reach. I'm trying to determine where the bracket actually is and the bolt that I need to remove. There is a bracket that peeks over the manifold and I took a photo using a mirror and hoping someone can tell me if this is the bracket and if not where I should look. Also, if that is the bracket is that the bolt that needs to be removed? (Looks too easy to me)

Yes that is one of the two bolts, I think you have the left side if I recall correctly due to that line on the bottom of the bolt. You need a ratcheting wrench if you want to get to them without taking the wiper cowl out, smaller hands are preferred otherwise it could be very tight.

Realizing that Lexus (Toyota) changes something every year, whether or not they need to, I'm a little skeptical whether that's the correct bolt. Upon further examination I think that secures a combination bracket and hose clamp (you can see the hose (or maybe wire bundle) running horizontally under the bolt. I guess all I can do is disassemble everything and find out. There is a great post by Alchemist with lots of photos although I can tell that his model is slightly different (his is a 2006 RX330).

Good news - Bad news
Okay, the good news is that the car now runs smoothly. The bad news is that I finally had to defer to my local mechanic (Cost $373.48)
Some notes for those inclined to venture into this realm...
First, the bracket that was peeking up behind the intake manifold (sorry, surge tank) was NOT one of the stay brackets. In fact the only stay bracket visible was the RH one, near the throttle body. Even after I had removed the throttle body and used a mirror to view as much as I could of the back side of the manifold (sorry, surge tank) I could not see any other bolts or brackets although I know they were there. I did unbolt the manifold (sorry, surge tank) and determined that somewhere there was at least one more stay or bolt holding it in place. At that point I decided to heck with it (or words to that effect!), buttoned it back up and took it to my local mechanic (specialty Toyota/Lexus) and let him do it. It was comforting knowing that he is honest and trustworthy and I thought the price was quite fair. He did tell me that year/model is the worst and he has special tools "bent to shape" to get at the back coil packs. Maybe that's why none of the other articles had to do with this model.
Sure wish I had gone there first because I missed out on two great days of golf!!! Oh, did I mention that I prefer the term manifold?
