K&N reusable engine air filters and cabin air filters let you avoid the cost and hassle of using disposable ones. But it’s important to keep them cleaned and oiled. Using a cleaning kit at the recommended intervals will keep your filters functioning well.
K&N’s air filter cleaners contain special formulas that get rid of dirt, dust, and other contaminants that build up over time. They dissolve stuck-on particles, which can then be washed away with water.
When you're done washing your filter, it's also important to reapply some filter oil. These oils are essential for capturing small dirt and dust particles. You can buy K&N filter oil in squeeze bottles and aerosol cans or in bulk sizes.
