In order to keep the internals of your engine working their best, you need to run an air filter at all times. Therefore, we at Huddleston Performance have created Air Filter Cups to fit various Carburetor sizes. These filter cups are made of 6061 Aluminum and are tumble polished to give a great finish. We offer these for the 33 mm, 40 mm, and 42/45 mm Mikuni Carburetors.

For our Outlaw racers we offer a High-Flow Filter Cup (See below Picture). This filter cup is designed with a concave internal design to increase air flow right at the Carburetor. These filter cups are made to fit the larger 3" Air Filters, also available through Huddleston Performance.

33mm Air Filter Cup - $12.95

40 mm Air Filter Cup - $12.95

42/45 mm Air Filter Cup - $20.95

High-Flow Air Filter Cup - $29.95

3" Air Filter - $30.00
