K&N PERFORMANCE POD AIR FILTER 4" INTAKE RU-2520

K&N RU-2520

K&N's Universal Air Filters are designed and manufactured for a wide variety of applications. Regardless of the angle, offset diameter of the air intake, there is a K&N Universal air filter 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 for up to 1/16" (1.5mm) to fit in-between sizes.

The Importance of Oil
A K&N Air Filter is made of 4 to 6 layers of cotton gauze sandwiched between two epoxy-coated aluminum wire screens.  The cotton is treated with a specially formulated grade of oil causing tackiness throughout the cotton’s microscopic strands.  The nature of the cotton allows high volumes of airflow, and when combined with the tackiness of the oil creates a powerful filtering media that ensures engine protection.
