Clean Every 50,000 Miles
This filter requires cleaning every 50,000 miles for highway use, more often in dust or for the lowest restriction. Thousands of microscopic cotton threads absorb K&N's specially formulated oil to create a powerful filtering medium. As part of their ongoing commitment to protect your Mustang's engine, K&N verifies its filtration efficiency using the ISO 5011 text protocol.
