K&N Replacement Air Filter
  • Designed to Increase Power
  • Million Mile Limited Warranty

Once again K&N delivers. I had replaced my factory air filter from Dodge on a 2013 Dodge Avenger R/T. Even though it was brand new, my vehicle had sluggish responses to acceleration prompts. Replaced it with ease with a K&N air filter. I took it for a test drive to compare and I could feel the massive difference in response. K&N is by far the best way to go when it comes to air filters. Plus, beating the price is nearly impossible for the quality and results that they deliver.

I have used and purchased K & N products, for over 20 years and have always been satisfied with the promptness in their delivery and the functionality of the product, itself. I will continue to purchase K & N products.
