Get some electrical tape and tape the socket to the extension. Which would be too late to do after it's down in there... but for next time maybe.

Yes, thank you from an LX owner.. similar process

 

I'm purchasing the Desno plugs from Amazon. Can someone please confirm if this is the right ones for our truck -
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.

 

The GX is probably one of these easiest vehicles to do spark plugs on, way easier than my old FJ, awesome write up!

 

Abatodu,do you have a part number for that filter?

 

[QUOTE=bauer26;7484396]Hi all, I've been lurking around these forums for a little while now and have gotten a lot of use of the information that is available here! Thought it was time for myself to contribute a little bit



Great write up,thanks for sharing.I am goinf to do mine soon,hopefully this weekend if I get teh plugs in time.

 

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!

Toyota gave me a price to change the spark plugs. Are you guys sitting down? $515.00.........I am in the wrong business! It cost me under $55.00 for the plugs.

 

I would think it is a 75 minute job tops to do the GX. The GS350 is easy and the GS300 is a nightmare with the in line 6, but I have done it 2 times

 

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.

 

Wow,just when you think you have heard it all.

In another post,I reported on what Toyota charges for a plug change.Today I finally got someone on the phone from Lexus on prices for the spark plug change.Cost of OEM Denso Iridium plugs was $53,no tax,free shipping to my door.

Toyota of Morristown..........$515.00

Tri-County Lexus................$649.00
