K&N Performance Cold Air Intake System: Easy Installation, Engineered to Maximize Airflow, Boost Horsepower & Torque, 57-2531

I did the installation myself and it was really easy. Took about 45 min from opening the box. The directions for putting the heat shield together was a bit confusing but you have to read carefully. The intake itself made my truck a little deeper sounding and the throttle response increased greatly. I can actually hear my turbo clearly now!:)

I own a Ford '97 F-250 7.3L. I Just got a new K&N filter intake system and put the factory one in the box of the K&N filter! Let me tell you something bro the throttle feels better with the intake. I'm able to get a better response from it and the turbo dude when I step on it lightly the turbo spoons and sounds loud just with this intake ,its funny when I make the turbo sound like that when I'm passing the Cummins and other people cause its loud and sounds like the 6.0 coming from a 7.3L plus it lowers EGT Temp. It's a must for the '97 F-250 Powerstrokes trust me. …just feels better knowing it just feels right. Thanks K&N

Easy to install took about 30 minutes to an hour. Very clean looking in the truck. Makes The turbo sound better

This was a perfect fit for my 95 Powerstroke. First-rate job by the designers at K & N. Kudos, Jay

The only negative is that it makes an already loud truck a bit louder. The instructions are quite good, but the photography is average at best. I am glad I didn't throw anything away from the old intake housing, because quite a bit of it was reinstalled. Truth be told, you saved my life, because no factory intake housings were available for love nor money.  Yes, I destroyed the previous one with starting fluid. My old F-250 Power Stroke should make it to 300,000 miles soon. Thanks.
