The K&N 57-2526-2 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 57-2526-2 air intake comes with an ultra-lightweight carbon fiber topped K&N high-flow air filter and a heat shield that installs into the previous air box space. Air is directed through an aerodynamically engineered intake tube into the engine’s throttle body for a guaranteed power gain. The tube accommodates the factory mass air sensor and a replacement silicone vent hose. 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 or less using existing factory mounting points. The tools needed are a screwdriver, side cutters, ratchet set and several wrenches. 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

Very Good Intake. Installed on my 2009 Ford Focus 2.0L SES. As soon as I started driving it, there was a great difference in power and sound. After about a week of driving, I noticed my gas mileage rose. The only problem we had was installing it, which took about 3 hours, but it was all worth it.

I have K&N filters in all of my cars and I love them. They hold up for years and they are easy to clean. This last one I bought for my Ford Focus was a bit difficult to install as it fit really tight. I like my K&N hat too.

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.
