  • When selecting one of K&Ns 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 applications inlet flange. The flange will stretch up to 1/8in. 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.
