Product Description
The kit replaces your vehicle's restrictive factory air filter and air intake housing. K&N intake systems are designed to dramatically reduce intake restriction as they smooth and straighten air flow. This allows your vehicle's engine to inhale a larger volume of air than the OEM air filter assembly. More air means more usable power and acceleration throughout the engine's RPM range. The filters on these kits are washable, reusable and easy to install with tools commonly available.

I purchased this for my 2003 F-250 5.4L gasoline truck. It was an easy install following the instructions which took me under two hours total. I have noticed a small increase in throttle response and a much deeper sound from the engine. I also combined with a flowmaster catback exhaust and a superchips tuner; with all three my truck's performance is much better than before the minor modifications. Overall I am happy with the purchase and would recommend it to anyone looking for a small boost in performance.

It has made a slight improvement in gas mileage, was hoping for more but will take any improvement. The power isn't really noticeable, but the sound says POWER! Get into the peddle, and you can hear what you like and paid for when you bought your vehicle, a strong running motor.

This thing draws more air than the factory setup for sure. I can really feel it come on about 1500 rpm, you can hear it sucking air from the cab. The fit is tight, but with some fiddling you can slip it into place. I have to say it was a little scarry when I opened the box and saw all the pieces that came with it, but it went together fairly quickly. I thing maybe an hour or so install time. Someone who does not mind trading a little extra noise for some more performance will like this product. Amazon had the best deal and had it to me in three days. I am a satisfied customer.
