The hood is the same. The changes are in the plastic nose pieces forward of that. I bought one for my '14 4R before the catalogs/websites had updated to show they would fit.
Yes, it will fit, but do you really have to install 5 years old deflector on brand new shiny truck? You can get AVS 25053 Bugflector II for $47.00. I had OEM deflector on my previous 4Runner, but this time I bought AVS and would never go back. Congratulations and good luck with your new rig...
I didn't get the 2016. The truck had less accessories than what I had now and the numbers the dealer promised me over the phone was no where near close to reality. So I walked away from the deal.
