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.

Great upgrade
By Joe Coyle
This filter system was a breeze to install - about 90 stress-free minutes. Imagine being asthmatic and taking a shot of an emergency inhaler; that's what this filter did for my 7.3L turbo diesel. The truck accelerates much quicker, pulls my fifth-wheel much easier and added a slight - but noticeable - increase in my fuel economy. My truck is a 2000 so I notice no increase in the cabin noise level. Should have added this filter system many miles ago. Amazon had it here a day after I ordered it. Five stars.

By TXk
2002 Excursion with the 7.3 diesel. Love this vehicle and will keep it forever. Already had a K&N filter, but broke a fitting on the air filter box when cleaning the filter. The cost to replace this part was almost as much as this new cold air intake unit and I didn't want a 10 yo part from the junkyard since it would have the same weakness of the part that just broke. It was easy to install and I am impressed with the performance. It is louder and it made me nervous that I had a leak, but after numerous stops to check I was sure that it was ok. The computer mpg shows a 2 mpg increase, but I have yet to check it the more acurate way. My hubby is happy that he now has my old K&N filter and it has improved the performance on his truck. I wouldn't have done this without the part breaking, but I am glad that this was my decision instead of going back to the original air filter box design.Update 1/9/12 - Still very happy with this and I am really getting an average of 2 additional miles per gallon. May not seem like a lot to most of you, but this vehicle costs over $150 to fill up due to the 44 gal tank. The idiot computer read-out shows that I am getting 22.7 miles to the gallon. Thanks to my super chip programmer, the mpg readout hasn't been accurate since I programmed it when the vehicle was new. I am actually averaging 18 mpg and I live in the hill country in Texas.

Recieved item much faster than I expected. Once installed I could definitely tell the difference in how the engine ran. Fuel mileage is up and life is good.
