Hand made in the USA and in the United Kingdom using only the finest materials, K&N OE Replacement Air Filters are washable and reusable.
Regardless of what you’ve heard, it’s almost impossible to wash your K&N Air Filter too much. Inside their testing laboratory, they have washed and re-oiled one K&N Air Filter more than 100 times and it still performs up to specification.
Depending on your driving conditions, K&N recommends cleaning your air filter every 50,000 miles.
To clean and re-oil, purchase the filter Recharger®service kit and follow the easy instructions.
