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 flange.
The flange 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.
