Filter improved Prius performance. Good filter. I would have rated it 5 stars if it had been 20 cheaper.

I have been buying K&N air filters for the last 10 years. Thank you guys for making one for my Toyota Prius.

As usual, the replacement air filter is noticeably superior to the OEM unit. My previous experiences in replacing filters on a 1980 Mercedes 300TD and two 1980s Volvo 145D vehicles indicate an increase in fuel economy and power during hill climbing. This was most obvious on the Volvos but could also be measured on the older Mercedes. Installation on the Prius was simple in itself but we have not yet driven it enough to check the fuel economy which is already 50+ MPG. There doesn't seem to be a measureable difference in horsepower but that figure may well be concealed by the operation of the hybrid system. I know for certain that the new filter will be beneficial simply because of the results with three other vehicles into which a K&N product was installed.
