"Perfect fit. Popped right in and the Yaris seems a little peppier as well. Haven't had a chance to check the gas mileage yet.
G" —Greg H from Charlotte, NC bought a K&N Air Filters for a 2009 Toyota Yaris, 1.5L 4-cyl. engine.
"I bought this car last year to save gasoline. When I decided that it was time to change the air filter, I could have just used a regular replacement filter. But I have used K & N air filters in my other cars and I thought it might just give this tiny car a little boost. I have not noticed any change in power (1.5 liter engine, so figure), but my mileage has jumped from about 36 mpg to 38 mpg. This is a 5% gain, just from changing the factory air filter to a K & N filter. That's like getting almost $0.15 off per gallon every time I buy gasoline. For the difference in price between the factory filter and the K & N, this is an easy decision." —Kenneth B from Monongahela, PA bought a K&N Air Filters for a 2009 Toyota Yaris, 1.5L 4-cyl. engine.
"I really noticed a big difference when I installed this new air filter in my 2009 Toyota Yaris such as increased gas mileage, acceleration, and a smoother engine performance!! Let your car breathe with this air filter and throw out the that factory asthma air filter." —Edgar F from Moreno Valley, CA bought a K&N Air Filters for a 2009 Toyota Yaris, 1.5L 4-cyl. engine.
