UNIVERSAL AIR FILTER SPECIFICATIONS
K&N
Universal Air Filters are designed and manufactured for
a wide variety of applications. Regardless of the angle, offset,
or diameter of the air intake, there is a
K&N
Universal Air
Filter available for your equipment. All filters are constructed
with ultra-strong molded pliable rubber flanges which absorb
vibration and allow for secure attachment, and can also
be stretched up to 1/8’’ (3mm) to fit in-between sizes.
K&N
Universal Air Filters are available in round, straight, tapered,
and oval designs.
