Customer Feedback

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.

I had bought an air filter for my 2007 V-6 Suzuki Grand Vitara. I just returned from a trip to Nevada. The trip is 2600 miles. We do this every Spring . We keep good records of the gas and mileage. With the new K&N air filter we got 4 miles to the gallon more. Also I had a lot more power. Good product. I have a 2010 Ford F-250 with a Diesel motor. Do you make a filter for this motor? One that will not have to have any modifications.
