2015 Lexus GX460 Spark Plug Change

Took a couple hours to perform the required maintenance on our 2015 Lexus GX460. This truck has been very reliable and needed almost no unscheduled maintenance in its 119k miles to date. Overall we would rank this is 3/5 job on the difficulty scale as it requires some time and patience, but isn't particularly complex.

This helped me a ton. I was deciding if it was worth my time. I'm taking my 2010 to a pro mechanic. Totally doable for me, but a lot of work and time for a few hundred extra bucks. I've found nothing ever goes as smooth in my garage as it does on YT.

Was quoted $800 to change my 2016 GX spark plugs. Its expensive to be lazy!

Just did mine, took me about two hours. Passenger plug near the firewall took the most time. Hard to get to it.

BTW, was quoted $875 from my dealer in NY.

Agree, that takes the oddest set of extensions and contortions to make work. That said, glad you saved yourself something like 800 bucks with doing it DIY - $875 feels pretty insane for the job which took me about 1.5-2 hours as a hobbyist.

My mechanic at the local Toyota dealership says only use Denso…he knows his sh*t. Just a heads up.

Those are OE but NGK Iridium’s are seen as equivalent and commonly used too. Doesn’t seem to be much consensus that one is dramatically better than the other. I did notice a slight uptick in fuel economy and the car seems to idle better. Either way, these are very stout engines and a good, quality plug from NGK or Denso will work just fine.
