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.

Good product as expected from K&N
By Riz
I've always preferred K&N products as they tend to fully test their products before releasing them. I bought this for my '94 F350 as my brother has one on his '93 F350 and loves it. The kit noticeably increased the horsepower of my otherwise stock 460. The gas mileage is only a little better, about .5 to 1 mpg). I was expecting a little better, thus my rating of only 4 stars. My brother (an engine tech) is suggesting my stock 460 needs headers and aftermarket exhaust to fully realize the benefits of the increased air intake that this kit provides.
