When selecting one of K&N’s universal round straight air filters, you should consider the following dimensions as they relate to the specification chart:
Mounting Flange Inside Diameter — This is the most critical dimension and should be very close to the diameter of the application’s inlet flanges; the flanges will stretch up to 1/8” for those in-between sizes
Filter Diameter: This is the overall diameter of the filter; always use the largest diameter practical to insure maximum filtration
Filter Length: This dimension is the length of the filter body only; it does not include the flange length; always use the longest filter practical for maximum filtration
Flange Angle and/or Length: If no angle is listed in the specifications table, the flange is straight; any angle listed is in degrees and can be utilized when space is a problem
Flange Type: The location of the flange in relation to the O.D. of the filter is sometimes offset to one edge of the filter for more clearance in an application
