Bought it for my 2014 Ford Fusion with a 2.0L Eco-Boost engine. Works great. I have K&N air filters in all of my vehicles. Great products

Bought this in 2015 for my 2012 Mazda 3 iTouring Hatchback w/ 2.0L Skyactive engine. What I've noticed is an increase in low RPM throttle response. I haven't been impressed with the 2.0L Skyactive engine in off-the-line acceleration before installing this K&N replacement air filter. After installing the filter (about a 5 minute procedure) I am noticing now that the gas pedal is more responsive with that initial acceleration from a stop. I no longer have any gripes about the Skyactive engine's ability to perform the way I want it to. But regardless, that fact that I don't have to touch this air filter for nearly 50k miles or buy another air filter makes me smile inwardly since I'm saving money and being more environmentally considerate. Such a small price to pay for getting so much from a little red air filter.
