      Comments about K&N Replacement Air Filter:

      Costs double of a paper air filter so it will take 2 years to recover the cost on a K&N. Seems well-made and my car idles quieter but it doesn't really improve fuel mileage on an older ford focus despite its claims. Nevertheless, the car idles quieter and if it's easy to wash/clean after 50,000 miles a K&N air filter will save money over time!
