HOW OFTEN SHOULD I CHANGE MY CAR AIR FILTER?
Under normal highway driving conditions, your car’s air filter typically needs to be replaced every 12-15,000 miles, which is approximately once a year depending on driving habits and conditions. If you commute through high-traffic, high-congestion areas, you might want to replace your filter every 6,000 miles. At that point, you’d need to throw away your used paper filter and purchase a new one. K&N High-Flow Air Filters™ are designed to last for the life of your vehicle, and are protected by a Million-Mile Limited Warranty. With normal use, they can go up to 50,000 miles before a cleaning is needed (the larger conical filters included with K&N intake systems can go up to 100,000 miles between services). Assuming your total engine life is 175,000 miles, and you replace your air filter every 15,000 miles, you would need just one K&N filter versus eleven disposable paper filters, which can translate to a savings for both you and the environment.
