great DIY. Today I changed sparkplugs of my 05 GX. This was my first try at DIY apart from replacing air/cabin filters.
I had 2 major challenges during the whole process
1) The spark plug socket was not coming out once I tightened the first spark plug and 6" extension came out instead. To overcome this I put the duct tape around the extension and the socket and things were fine after that.![Big Grin](https://www.clublexus.com/forums/images/smilies/biggrin.gif)
2) Removing the cable which was attached on top of the spark plug assemble was the hardest...took most time to pull that out so I can remove the head...and I could never figure out the easier way throughout the 8 plugs.
I got torque wrench as well but never used it. Just tightened it based on what I felt while removing the plugs.
But finally it looks good and hopefully it will be fine.
thanks!!!

You DIY Spark Plug for 04 GX470 was GREAT! Because of your write-up it took me only an hour to change my plugs without any problems. I just turned 200,000 miles on my GX....have you changed anything else that would help me? Thanks for your post
