Rated 5 out of 5 by Awsome Product Very good product. I have personally used K&N product for past 20 years in different cars. And I have been 100% satisfied with K&N. However the part number in the K&N catalog is wrong for the 2016 Toyota Prius. For the cabin filter and the engine air filter. October 17, 2016
