ITG air filters use a three-stage foam for excellent airflow with great filtration. The ITG "Megaflow" line of racing air filters have distinctive red plastic bands around the top and bottom of the filter element. The JC20 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. Baseplates are sold separately.
