ASTOUNDING INCREASE IN MPG FOR MY 2007 SHELBY GT 500 MUSTANG

Just wanted to advise you guys that K&N FILTERS are the best filter on the market, and that you guys are by far the best by any test, and way ahead of the rest.

Ordered my K&N FILTER from the K&N on line store, and rcvd it by "BROWN"(UPS) in the specified delivery time frame. What a combination of partnering & customer service par excellence. I hope that you guys are ready for my testimonial, because I am just totally blown away by the fuel economy that I have received. Prior to installing my K&N FILTER, I was shifting at the indicated shift point, which calculates to approximately 1,800 RPM's., but I was only receiving 15.9 to 16.90 MPG.

Upon installation of the K&N PANEL FILTER in my 2007 SHELBY GT 500 MUSTANG, I am now enjoying the incredible fuel economy of 18 MPG. I must also admit that I have seen 19.4 MPG. Of course being the RED BLOODED, and HEAVY FOOTED driver that I am, the MPG does drop to 18 MPG. I should also mention that my motor only has 3,290.00 MILES on her. I reckon that makes her still a virgin, and she has quite awhile before she is totally broken in. Anyway guys, I am at work, and must go, and once again, hats off to the K & N FILTER GANG.

Best regards,

I used this filter as a special Air Cleaner replacement for a 1955 Ford Thunderbird that otherwise would normally have an Oil Bath air cleaner. There is a company that makes air filter cleaner replacements for the old Oil Bath cleaners and I upgraded the included air filter to a K&N Filter, and I am happy with the results. For anyone else that has a 1955 or 1956 Ford Thunderbird with the original Oil Bath cleaner, you can upgrade to an air filter cleaner assembly from (Brand Name) and then upgrade the air filter to a K&N. Hope this helps any fellow '55-'56 T-Bird owners.

Installed the K&N 63-2587 on my 2014 Ford Fiesta ST. Installation only took about a half hour & was simple following the step by step instructions. The K&N cold air intake provides better throttle response along with a cool sound. For those who are worried about heat soak, its only s couple degrees higher than the restrictive factory air box. The only way you would get heat soak is if you were stuck in traffic in 100 degree weather. I live in New Jersey where it can get 90 plus degrees with high humidity & I have never had an issue. I have no regrets putting this on my car. It was money well spent. You can feel the difference as soon as you drive it.
