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.
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!!!

Thank You
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
