ITG air filters use a three-stage foam for excellent airflow with great filtration. These filter elements are the domed version of the ITG "Megaflow" JC20 series racing air filters. This sausage style lacks the distinctive red band on the top of the standard Megaflow filters but retains the 3-stage foam. The bottom frame on this JC20SB version is black for a stealth look.
The JC20SB series is designed to fit a single carburetor (such as Weber DGV, DCOE, IDA) or 1 or 2 throttles on a fuel injection system. The element measures 5 7/8" wide x 7 9/16" long. The nominal height in the part number refers to the internal height in millimeters. Choose a size that leaves a gap between the filter and air horns of at least 19mm (3/4") for street or 32mm (1 1/4") for race applications.
Baseplates are sold separately. Filter elements sold individually.

Sold individually. Each element includes one quick-release fastener. Baseplate sold separately.
Note: ITG filters are supplied dry and must be oiled prior to use. ITG recommends the use of Rock Oil Eco Foam Air Filter Oil (Part No. 3818-001, sold separately). Extensive testing of Rock Oil against other foam filter oils has shown that ITG filters treated with Rock Oil actually outlasted filters treated with other oils (including brands previously recommended by ITG)!
