I have the engine air filter and the cabin air filter. These are quality products. The engine air filter has added a couple of MPGs to my mileage. And the engine feels just a bit smoother around town. The cabin air filter has added a nice crispness to my car interior air. These products work and are well worth your hard-earned cash.

Perfect fit for 2017 prius. In the past I have gained a couple mpg with K&N air filters.....lost a couple mpg so far, hopefully will improve.
