Did a lot of searching here for the spark plug change on the 2014 model but came up empty. Lots of spark plug info but no how too. The video I linked is on a 4runner but everything looks the same under the hood as my TTUE. Everything is straight forward with only one word of caution. When separating the air pump from the metal tube make sure you secure the thin metal gasket and don't drop it like I did.
Replaced with Denso oem plugs. Four made in US and two from Japan. The plugs made in the us had a metal puck which looked to have a circular weld around it on the ground strap when viewed through a jewellers loupe. The Japanese plugs looked spot welded and the puck was not as prominent.
