Installed a K&N filter on the 2nd day I bought my new 2012 Prius. I always get about 60MPG on the highway. Even city MPG is in the high 50MPG. I don't know what the original paper filter would have given me and don't really care. K&N air filters rule the road!

100 satisfaction. This is the second Prius installation I've done. First, a 2007 Prius with a K&N filter provided over 100,000 miles of satisfaction . Most recent K&N filter installed in our 2015 Prius. Regards, Reg.
