Hi Folks,
The maintenance schedule says to change spark plugs at 120k miles or 144 months. Car runs fantastic with no issues. Any prudence to changing the spark plugs early? I was also thinking of changing the coils and the air/fuel sensor for bank 1 since it will be taken apart and more easily accessible.
Thanks again for all of your help!

I would wait until 120k. It takes me about 2.5 hours to do this on my daughter's Avalon and on my wife's Avalon. I did put new OEM coils on the rear plugs of my daughter's when I did hers since she puts a lot of miles on her car every year. I saved the old ones as spares. The front ones are super easy so I did not swap them. It's a coin toss in your situation since it appears you drive 10k or less a year. The original coils will likely last long past 120k but, if a couple hundred bucks is no sweat, might as well swap the rears out while you have the manifold off. Be sure to use OEM if you do.
@oldandy Thanks for the advice. I will consider waiting since I pulled the front bank of plugs and they looked to be in good condition.
