The K&N Kart air box for Karts works with one of two K&N High-Flow Air Filters. The K&N Kart Airbox works specifically with Kart vehicles that are involved to increase air flow and maximize power. Air filters are sold separately. Either filter will be attached into the RK Kart Airbox and then the whole assembly is connected to and attached on the carburetor.

K&N Engineering is a manufacturer of cold air intake systems, air filters, oil filters and other aftermarket performance parts. They manufacture over 6000 parts for various cars, SUVs, trucks, motorcycles and more. Founded in 1964 by Ken Johnson and Norm McDonald, hence the name of the company K&N. The duo first sold motorcycles and motorcycle parts and also supported K&N factory race team. Not long after, they saw a need for air filters that can perform under extremely dusty and dirty conditions which prompted them to move into air filters, and that quickly became their primary focus. They have maintained an active involvement in racing over the course of their history. Including the King of the West 410 Sprint Car series and NASCAR series East and West. This on its own shows pedigree, and the quality of products being churned out from their factory.
