K&N Racing Assembly Combines Durable Construction With Superior Performance

The K&N 100-8593 custom racing assembly offers maximum airflow for greater horsepower.

It includes an air box constructed of ultralight and durable K&N generation 2 carbon fiber that is durable enough to take the extreme vibrations and engine heat that always results from achieving maximum speed. Yet, as it withstands the upheaval it delivers superior airflow and is designed to increase horsepower. The rectangular air filter features multiple layers of cotton gauze media, which has been treated with a special grade of filter oil that make the strands of the cotton extremely sticky.

The air box has air horn seals for better insulation and easy installation. It is ideal for racers who drive racecars that use traditional multi-Siamese stacks.

It’s no accident that K&N uses carbon fiber in the construction of the assembly. The composite has been treated to deal with extreme heat from less than 0° up to 2500° Fahrenheit and is engineered with specific resin systems for application specific needs. To work properly there has to be a balance of fire retardant resins and ceramic blends so the component can withstand the intense heat and yet be flexible enough to avoid damage.
