The K&N 57-2559 FIPK air intake system replaces the restrictive factory air filter and air intake housing in some Ford Focus models. K&N intakes are designed to dramatically reduce intake restriction as they smooth and straighten air flow. This allows your engine to inhale a larger amount of air than the factory air filter assembly. More air means more usable power and acceleration throughout the engine’s RPM range. The 57-2559 air intake comes with a K&N XStream Top air filter designed for higher air flow and durability. The air filter installs into the previous air box space and directs air through an intake tube into the engine’s throttle body for a guaranteed power gain. The tube accommodates the factory mass air sensor and crank case vent line. The oversized cone shaped air filter comes with a water repellent DryCharger filter wrap to protect the filter from moisture. The air filter can be used for up to 100,000 miles before servicing is needed depending on driving conditions. This air intake is relatively easy to install usually in 90 minutes or less using existing factory mounting points requiring commonly available tools to do the job. K&N 57 Series FIPK's are street legal in all 50 US states and come with K&N's Million Mile Limited Warranty.

I love this air filter, the way it makes my 2014 Ford Focus ST sound and perform is amazing. Can't thank my amazing girlfriend enough for getting me this, this past Father's Day. Awesome product.

This isnt so much about the improvement of filtration as is it about the durability.I was changing the oil in my 2010 Ford Focus and I took my K&N Air Filter out to wash it.As I normally do I have a back up stock filter to put in my car while my K&N dries overnight.Not thinking as I backed out of the garage I drove over top my K&N flat panel filter drying in the sun.I reluctantly got out looked under the car and there it was tire track straight across the filter and not even a dent in the screen on it I was amazed.I had to write an tell you about how what could have been a catastrophe turned out to make an even bigger believer in K&N filters out of me I have one in my truck, My race car, my Focus and my fourwheeler.Id never be without one Thanks Again.

Installed on a 2014 Ford Focus ST. I couldn't be happier! Very easy to install and super fast shipping. Noticeable throttle response improvement. Much better sound than stock filter (which can only lead one to believe it has much better air flow). Nearly 4mpg gained (VS stock filter, data gathered over 2 weeks, driving the same route at roughly the same speed 7 days a week). All and all I couldn't be happier. I've been so impressed with it that I talked my dad into getting one for his 2010 Titan. You get a nice little K&N decal in the box with this one. I stuck it on my airbox :D.
