K&N Universal 4" Flange / 9" Tall Air Filter

The 4’’-Flange and 9”-High universal air filter is made of cotton gauze and is designed to be washable and reusable. K&N universal air filters are constructed with ultra-strong molded pliable rubber flanges that can absorb vibration while providing a secure attachment. The rubber can also be stretched between sizes for optimal fit. K&N air filters offer high airflow, excellent filtration and long service life.

The K&N RE-0870 4 inch flange and 9 inch tall universal air filter is backed by a 1-year/unlimited mileage warranty against manufacturer defects from the date of purchase. However, if the filter was purchased as a direct replacement for a K&N air intake system, it is backed by the 10-year/million-mile limited warranty.

If you purchase a K&N RE-0870 universal air filter, the package will contain one filter that is 9 inches in height with a six inch diameter base, a 4.625” diameter top, and has a 4” flange that is 1.75 inches long.
