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!

Works great! Increased 1-2 MPG on my 2013.

I've used K & N air filters since the 1960's with no problems. Currently I have the cold air intake system on a 2003 F250, a 2010 Prius replacement filter, just ordered a replacement air filter and a cabin filter for a 2014 Prius.
