This filter was a perfect, drop in fit for my 2012 Toyota Prius. I couldn't find an aftermarket filter to fit my car, and decided to spring for this permanent filter. It seems to work very well. I haven't had it long enough to compare mileage figures with the oem filter yet.

Installed this on my 2017 Prius 4T and immediately noticed an increase in acceleration and an extra 2-3MPG. Transition between electric and gas motor is now virtually silent. Smoother engine dynamics. Easy to install. This is a simple, low cost way to improve your car's performance and mileage. Highly recommended.

I have not seen much of a savings since I installed your filter.
