Came with all necessary supplies. Seemed to be of good quality and my taco is running well after the oil change. Will buy again.

Works Fine, Fits Fine
Size: (Pack of 1)
Seem to work and fit just fine and should be better than a cheap paper filter. They cost more but I change the oil on the 5's and the filter on the 10's so it evens out. Not going more than 10K on the filter. If you are only going to use the filter for 5K miles I would stick with the Toyota factory filter. I use the K&N filters on a 2017 Toyota Sienna and a 2018 Toyota Highlander. Both are V6

This is my go-to oil filter for my 2015 Toyota Sienna minivan. The filter looks good and holds up well. I have no idea how well it actually works, but it looks good.
