K&N Performance Cold Air Intake System: Easy Installation, Engineered to Maximize Airflow, Boost Horsepower & Torque, 57-2519-3

Subject: Performance Truth Dear K&N, This past month I purchased a replacement filter for my wife's 2003 Ford Escape and what a difference it made, power you can feel. The Escape now to me has better throttle response. On another note my 2000 Mustang GT was also greatly helped by the FIPK 57-2519-3 P/N. It too had better throttle response over the K&N filter replacement. When the replacement filter was dropped in the canister the car did better than the stock filter, but then I installed the FIPK and WOW!!! what a difference. The other positive was the detailed instruction that had picture after picture that showed every detail. My father and I installed the FIPK in about 90 minutes not rushing. I have purchased many things but not with instructions this simple. Thanks K&N. PS My father was so impressed with the drop in filter in my wife's Escape that he had me go order a K&N replacement filter for his 1991 GMC. Another positive, my assigned POLICE car, a 1997 Crown Victoria, has a K&N drop in filter that I purchased on my own, it too made a difference. Thanks again for your time and engineering. Job well done.

I purchased the FIPK System after reading your testimonies and a little research and what a great product. I have a 98 Mustang GT (5 speed) and had it installed easily within an hour. After I installed it I took it to a side road here in Chicago and noticed an instant improvement in power. As I floored it and ran through the gears I even noticed different sound from the engine now that it can breathe properly. It's too soon to tell on fuel economy but then again I own a Mustang and who buys a sports car for that. Great product-great engineering,

Breathed new life into my 2001 GT Mustang! With a few other improvements the car runs stronger and idles smoother than it has in a couple of years. Always used an in-box K&N filter before, but the cold air intake makes a real difference. Easy to install and was surprised there was no excessive noise when running. This car is a keeper now!

I just wanted to say a big thank you for the new K&N Fuel Injection Performance Kit 57 series. I installed this system on my 2001 Mustang a few weeks ago, and I must say this product is wonderful. I admit I was slightly skeptical of what, if any, difference I would feel with this system. But I knew K&N was a respected name, so I thought it was worth the try. On the first test drive I dropped it into 3rd gear on the open road and I could immediately hear a HUGE suction of air rushing into the engine like crazy. The whole system sounds strong, and it really made a bigger difference than I thought it would! Amazing what a little bit of extra air can do for an engine. Oh by the way, it now barks the rear tires dropping into 3rd gear at 60 mph on the highway. Yes!!!!! Thanks again!

Great product. Great price. Fixed my issues with my old cold air and I can feel the boost of power.

Kind of expensive. But after few weeks of driving it's very well worth it

Awesome product! Delivered fast, increased power and gas mileage. Worth the money.
