How often should I clean my K&N air filter?

The cleaning interval depends on your driving conditions. K&N recommends inspecting the filter regularly and cleaning it when you see a buildup of dirt and debris. In normal conditions, cleaning every 50,000 miles is a good starting point, but more frequent cleaning may be needed in dusty environments.

Do I need to oil the filter after cleaning?

Yes, K&N air filters rely on a light coating of oil to trap dirt particles effectively. After cleaning, you'll need to re-oil the filter with K&N filter oil to restore its filtration properties. Be sure to follow the instructions on the oil to avoid over-oiling, which can damage your mass airflow sensor.

Is this filter street legal?

Yes, this K&N air filter is street legal in all 50 states. Because it's a direct replacement for your factory filter, it does not require any modifications to your vehicle's emissions system.
