K&N has several types of intakes that will completely replace the factory airflow assembly including the filter, air box and air path. More and more people are discovering the monster power available from a well-engineered air intake and K&N sells over 500,000 air intakes every year, so go ahead and wake the sleeping giant in your car.
I installed this intake in an otherwise stock '07 F-150. The HP increase is definitely noticeable and it sounds like a beast under the hood. I also went from 10mpg city to 13.5mpg city. Havent done enough highway driving yet to see the difference. Great product, thanks!

5.0I only buy K&N for a reason
I've had this kit for a couple years now, and I've never looked back. Quality parts, fairly easy install, and noticeable performance gain. First time I drove with this kit it was night and day. Immediate, major increase in throttle response and power, got rid of the bulky restrictive factory system, and I love the sound. You can hear the suction in the low-end, and it sounds a little throaty when you get on it. I also highly recommend getting the "Recharge Kit" somewhere down the line. Keeps the filter in great shape over time, especially if you're in a dusty area. Overall great product, should be one of the first things you put into your F150.

This kit is great! It comes with everything needed and the best part is it increases miles per gallon and horsepower! If your debating to get it or not, get it!

This kit is easy to install and shouldn't be a problem for even the most novice mechanics to install. It makes a noticeable difference in power and mpg. The only gripe I have is the noise. It's a little loud when you are hard on the throttle and under a load, like when towing.
