Old thread, I know... really want to change the spark plugs while waiting for my ecu to come back from PA (sent 2/9 via usps "2-day priority mail", yeah right).
Could anyone out there advise the torque spec for the plugs?

Thanks guys in advance.

yep, i did 15
make sure you do all 8 correctly . some will be tricky to get the tool in right to get the correct spec but its possible.
Has any tried both of the spark plug setups? I'm so use to using 1 step cold plugs for turbo applications. Trying to decide which one to go with. Full bolt on exhaust mods if that makes a difference.

I'm curious also. Is anyone running 2 step colder plugs all motor? I'm wondering if they would foul at all.
I changed my plugs Saturday evening. I got the Denso FK20HBR11 Iridium plugs from Advance Auto for ~$120 using a 25% off promo.
What a PITA!
Obviously, it's not a very complicated task in and of itself. It's just very tedious & time consuming to figure out some of the access for the first time with that packed engine bay. Also, it would have helped if I'd gotten the shorter plug socket with integrated swivel extension. Craftsman makes them with a 6" or 12" extension.. I wanted the 6" version because I already have plenty of other 3/8" extensions if needed. However, my local store was out of stock, so I settled for the longer one.. That proved to be a bit difficult for some & downright impossible for a couple. I did have an old spark plug socket in the appropriate size.. The problem with that one was its rubber core holds on the the plugs very well, and the socket doesn't connect to my extensions very securely. So, once a plug had been tightened, the extension would end up coming out sans socket because it grips the plugs so well. In hindsight, I should have tried using a standard deep socket & perhaps a little bit of tape or something to secure the plug while installing..
Anyway, I digress..
I'm amazed by the results! It feels like I got a new engine! It starts quicker, idles smoother, pulls harder, and it's even a tad quieter now. It just feels great all the way around. I can't wait to get her out on the track this spring.

NOTE: I had just under 56K miles on the the original plugs.

Next time, which will be a while, try a magnetic spark plug socket. I used to have the same problem as you with the rubber not letting go of the spark plug and coming off the extension. The magnetic socket works quite well and I've not had a problem since, though I'll admit I haven't had to do a spark plug swap on the F yet.
I need to change mine as i don't think previous owner did based on the lexus service history; i'll have to check it again as i also don't think the 60k mile service was done either. I might have to farm out the work though as the F is a PITA for me to work on.
I have to do mine come spring, not overly looking forward ti it. Ive had to do my IS250 twice, im hoping the F is equally or less didficult. That magnetic socket tip is good, ive had the same issue noted above when doing my 250 with the rubber socket insert.

Oh yeah, the magnetic spark plug socket is great.. That's what I got from Sears.. The problem is the integrated 12" extension on it is too long for some of the IS-F plugs, so I had to resort to my old socket with the rubber insert. The 6" version of the magnetic socket is definitely the way to go. In fact, I'm going to do an exchange once they're back in stock at my local store.

The one have is actually just the spark plug socket, no extension on it. Figured this would allow me to pick and choose how much of an extension I would need.
I know most of you would never pay those prices for this extension, and I understand. I use this tool on a regular basis for my work. It worked perfectly for my car, and many other cars that have tight spaces and the sparkplug socket wanted to stick to the spark plug.
You most likely could find something from craftsman (or any other brand you prefer to use) that would work just as well for you when you are doing the spark plugs for your car:
While we're talking about tools, the proper size for the spark plugs is 16mm. Good luck finding a quality 16mm spark plug socket in the US. 5/8" is within a few thousands of an inch, and what everyone seems to use for 16mm plugs. And while we are there, 5/16" is interchangeable with 8mm for the exact same reason.
