The K&N 57-2507 FIPK air intake system replaces the restrictive factory air filter and air box in some Ford Probe and Mazda MX-6 models. K&N intakes are designed to dramatically reduce intake restriction and improve 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 57-2507 air intake comes with a chrome topped K&N high-flow air filter that installs onto the factory mass air sensor within the previous air box space. Air is directed through the air filter into the engine’s throttle body for a guaranteed power gain. The oversized cone shaped 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 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.

Customer Feedback

Be the first to review part 57-2507
After reading other reviews I decided this was the intake for my 2013 Ford Focus with the 2.0L Duratec engine. Great sound and noticable performance, plus better fuel economy. The numbers don't lie. The provided dyno info was almost exact when I had put mine on the dyno. Nearly 10hp gain through the meat of the power curve.

Installed this product on my 1991 Ford F-150 and what a difference it has made. Definitely gave it more power and about 3-5 mpg better. This was a want for this truck, now a NEED for my other vehicles.

I installed this intake on a 2015 Ford Focus Sedan SFE 1.0L EcoBoost. What a difference The kit is just a filter and a new intake box lid, so you won't get the loud CAI sound....but the throttle response is AMAZING MUCH more fun to drive, much smoother acceleration. Less bogging when the rpms dip too low. Couldn't be happier
