Since I bought a K&N air filter for my 2011 Toyota Prius(which I did not install until almost a month of receiving same) and realized that it gave the car much more get up and go I decided to buy one for my wife's 2012 Toyota Prius. Yes, you guessed it, it has not been installed as yet due to the miserable weather we are having. It will be installed this weekend and I will expect the same results for her car. It will also be interesting to see if we also get better gas mileage.

I've used K & N air filters since the late 1960's and have had positive results.
