Kool Blue™ is the new name in high-performance air filters from American speed equipment manufacturer ACCEL, and available in the UK through Bedford-based USAutomotive and other selected outlets.

Kool Blue air filters have been developed as an original equipment, high-performance replacement filter for a vast number of new and older vehicles, but are also offered in a multitude of sizes covering one-off custom and racing applications. For more extreme applications, ACCEL has developed the Kool Street filter which sits atop any American 5 inch diameter carburettor neck.

Kool Blue air filters have been tested to offer superior flow and filtration to any competitor and produce extremely high flow rates, maximum filtration and long filter life. They are the only filters proven to protect engines against particles as small as 2.8 microns.

The performance of paper and foam filters deteriorates quickly . Kool Blue filters are washable and re-usable to maintain efficiency and with care and maintenance will provide maximum airflow and increased horsepower for over one million miles.

Kool Blue air filters are available in the broadest range of applications of any air filter in the US and cover models from a wide number of worldwide automotive brands.

Kool Blue Air Filters are an o/e replacement fit for selected models from the following manufacturers.
