More surface area for 10% more air flow…means more horsepower and better fuel mileage. TUV rated at 99% efficiency, while stopping particles as small as 2.8 microns resulting in longer engine life.

Precision layering of cotton produces highly consistent filtration rates with less restriction than competitors’ filters

Kool Blue air filters use four layers of 100% surgical cotton gauze, similar to many other filters on the market. However, the use of modern methods of layering material deniers makes these filters significantly more efficient and consistent throughout the production, resulting in stopping more dirt which saves engine wear.

Advanced rubber compound provides better sealing and more surface area for unparalleled filtration and performance

Another benefit from this advanced rubber compound is less bleeding into the cotton during the manufacturing process which results in as much as 10% better air flow than competitors’ products. More air means more horsepower potential and better fuel mileage.

Unique galvanized steel mesh construction provides unequalled durability, flexibility and longer life

Kool Blue filters use a galvanized steel blue plastic-coated mesh which provides a stronger, more durable filter which is less susceptible to damage. The competitors use black painted aluminum that can easily damage during installation.

Plastic-coated mesh for protection and long lasting beauty

The blue plastic coating makes sure that the filter will always maintain its bright blue appearance (particularly when universal filters are used in place of the air box) even after cleaning many times.

Washable and Reusable which means you save money

Kool Blue filters are washable and reusable using a Kool Blue filter cleaning kit. Under normal use, a Kool Blue filter will go 50,000 miles before cleaning is necessary.
