K&N Air Filter Maintenance
Keep your filters in tip top condition
K&N air filters are washable and reusable. They are easily cleaned and oiled using a K&N Recharger kit. They can be cleaned and oiled as many times as reasonably necessary. In their testing laboratory, K&N have washed and re-oiled a K&N Air Filter more than 100 times and it still performed up to specification.
NOTE When servicing a K&N filter, take care not to over-oil the element. Besides impeding air flow, excess oil can migrate into the intake system where it can coat electronic sensors, which some OEM's claim may hinder the sensors' operation and result in a repair that will not be covered under warranty. Although K&N disagrees with such claims, in order to avoid a dispute with an OEM over the denial of a warranty claim, we suggest that you be careful not to over-oil your K&N air filter. Never saturate the filter. If oil drips from the filter, wash it and start over. Use only K&N oil. For example, an E-1500 filter has 92.4-inches of surface area requiring 1.707 fluid ounces of oil. Follow oiling instructions included with your filter.
