The K&N 57-2569 Air Intake fits some Ford F150 models. See vehicle applications link for details.
The K&N 57-2569 FIPK air intake system replaces the restrictive factory air filter and air intake housing in some Ford F150 models. K&N intakes are designed to dramatically reduce intake restriction as they smooth and straighten air flow. This allows your F150’s 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 57-2569 air intake comes with a chrome 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 crank case 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 the existing factory mounting points and requires 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.

My butt dyno can't verify any HP gains. However, it has improved throttle response, as well as a slight increase in gas mileage. Gave the motor a throatier sound, too. Overall, I'm happy with the purchase.

Just got the kit today. Unfortunately, I'm laid up for a while, so the install is going to have to wait. As of now, I have no complaints. Shipping was fast, price was right. If, down the road, I have any issues, I'll be back to update. If not, consider this a positive review of the products performance, as well.

Super easy to install. Fit my 06 f150 perfectly.

Easy to follow instruction, immediate response on performance, and deep throttle response when you kick it. Great addition to my 2006 F150.

WOW. I usually avoid the hype connected with any products claims, until I have a chance to try it out for myself. Installed my performance intake kit No. 57-2569 on 4.29.15, and on my first test drive, I thought someone had installed a larger engine in my 2006 F150 4.6L while my back was turned. Sound is dynamic, and there is no doubt the horsepower increase is 10 plus. Thanks for such a great product and I am now a K&N customer for life.
