Which rear coil? It is really a question of access, set of tools and size of your fist.

Check the thread on replacing the spark plugs on rx300.

just replaced a second bad coil on my 07 RX. this one was on the middle cylinder. first time happened about a year ago on one of the rears. took it to toyota to do the job since getting to those is a complete pain.

closest Dealer is 130 miles away from where i live and asked about $300 to repair. from my online research i found that the part is only $45 at Amazon... (Beck Arnley 178-8311 Direct Ignition Coil). I opened up the hood and the plastic cover. there are three circular kind of things with off-white translucent stuff on top (why OEM parts dont have it ) ... png image hosting
My question is :
1. is the middle one coil D.
2. is that the right part i found on amanon LINK HERE
3. what is the other small circular connector or part right under the middle one of those big off-white gas cap kind of things (not sure if those are the front Bank / 3 cylinders and external part of the coil)
4. Can i change is by my self (is it hard/ risky)
PLEASE HELP by shading some light , i am lost and confused.
thanks in advance and your answers are much appreciated.

Did you have solution to this? I am having the same identical problem.

The last # tells you what cylinder has a issue.....In the OP its #4 which is on bank two. 1,3 & 5 or on bank one & the even numbered is on bank two. A quick way to tell which side is Number one cylinder on any V engine is the cylinder that is sticking out farther.....
