How the 2021 compares with nearby years
Against the 2020 Tundra: the two manuals do not print the same part types, so there is nothing to compare line by line.
The 2021 Tundra belongs to the 2nd gen (XK50), which began with the 2007 model year (MY2014 redesign; MY2018: LED headlights optional); generation dates. Parts often carry over within a generation, but the manual for your exact model year is the one to trust.

What the manual does not print
The 2021 Toyota Tundra owner's manual does not list wipers, battery and filters sizes; for the battery, read the label on the battery fitted to the car, then check the size against the BCI group chart; for wipers, measure each blade end to end and buy the nearest whole-inch size.
Buying the parts for a 2021 Tundra
- Small bulbs: this manual names 10 replaceable bulb positions. Wedge bulbs such as W5W and 194 differ from twist-socket bulbs such as 7443 or 3157, so match the full number, including suffixes like NA (amber).
- Oil: ILSAC GF-5 SAE 0W-20, 8.5 US quarts with the filter. Use the grade printed for your engine if the manual lists more than one.
Check it on your car
