I'm pritty sure it is, but just want to confirm for peace of mind.
Thanks.

Changed the plugs on my 07 yesterday. Took a solid 2 hours mainly due to the difficulty unclipping the coils. Runs buttery smooth now. Also dropped in an AEM air filter.

Changed the spark plugs this afternoon.I spent a lot of time on the plug closest to the firewall on the drivers side. The passenger side was a piece of cake once the airbos was removed. I found it easier unclipping the coil packs. I also put a dab of dielectric grease inside the boot and sprayed thte coil pack connection with DeoxIT.
The plugs did not really look that bad outside a little bit of debris on the insulators.The gaps on the plugs were at .044 except one which was at .046. We bought this truck 6 years ago,CPO with 52,000 miles on it. I very much doubt the plugs were changed before we bought it. Today,the truck has 142,452 miles,all on the original plug I believe.If so,I am really impressed by that.
Thanks to the original poster and everyone else for their input within this thread!

I did not ask their book time,but,they can surley do it faster than I can. It took me 2 hours,but doing it again,I could knock 30 minutes off that time. I also clean things as I go along.

I was just quoted around the same price- about $500 for the spark plug job- and that is at a TOYOTA dealership! WTF They told me the manifold had to be removed to do this, and thus the high cost. If 2hrs of labor is needed, I still don't see how this job costs more including parts than $250-300. And I thought toyota was to be cheaper than Lexus labor rates?!
Can't say I'm pleased. Needless to say I declined their offer to change them.

MANIFOLD DOES NOT COME OFF. Find yourself a new dealer! 1 hour job. Plastic cover comes off. Remove coils, replace plugs, replace coils, put plastic cover back on. Oh, I think I needed to remove air filter box on passenger side for access.

Toyota of Morristown..........$515.00
Tri-County Lexus................$649.00
