"While it does not deliver the performance upgrade of a full intake system, for the price it is hard to argue the value of this filter, especially considering the cost of stock replacements compared to this reusable filter. I cannot report on MPG gains yet, but I will say that throttle response seems to have improved slightly." —Jerry P from Hemphill, TX bought a K&N Air Filters for a 2012 Ford Focus.
"Easy install, lifetime value, great product!" —Cory H from Fort Worth, TX bought a K&N Air Filters for a 2012 Ford Focus.
"When I opened my shipment box the filter had a few small dents which I was able to pinch and straighten out for the most part. I noticed an immediate improvement in throttle response and less surging at all speeds. My mileage has improved from 29.1 to 30.8 (may not be fair as the engine only had 538 miles on it new when I installed the K&N filter) but I've had good luck in the past that's why I bought another." —Michael M from Waterford, CT bought a K&N Air Filters for a 2012 Ford Focus.
"Installed into my new 2012 Ford Focus SEL and boy do I love the sound! On a recent trip I got 41 MPG instead of 39 before installation." —Mark S from Endwell, NY bought a K&N Air Filters for a 2012 Ford Focus.
"great as always from k&n perfect fit good purchase" —Andrew V from Goose Creek, SC bought a K&N Air Filters for a 2012 Ford Focus.
"I've been using K&N filters in my vehicles for 15 years and have always been satisfied with the product. One of the first things I did when I got my new 2012 Focus home was to change the Filter to a K&N." —Frank E from Macomb, MI bought a K&N Air Filters for a 2012 Ford Focus.
"Easy installation and cheap horsepower. What's not to like?" —Zachary R from North Wales, PA bought a K&N Air Filters for a 2012 Ford Focus.
"The Ford Focus 1012 Titanium OEM filter is the same size and shape but cannot be cleaned." —Pedro A from Fresno, CA bought a K&N Air Filters for a 2012 Ford Focus.
"On our 2012 Ford Focus I immediately noticed a nicer engine sound and what appears to be slightly better pickup. However for my 1998 Ford Ranger 4 cyl, I did not notice any performance improvement; that said, it passed the smog test with excellent numbers, which may or may not have been improved by this filter. My vehicles will always get an upgrade to K&N!" —Jose A from Victorville , CA bought a K&N Air Filters for a 2012 Ford Focus.
"It took some MacGyvering, with a socket and screwdriver, but I'm very happy with mpg and extra step." —Warren F from Vacaville, CA bought a K&N Air Filters for a 2012 Ford Focus.
