Constructed using the same premium materials used in our Cold Air Intake Kits, these filters offer significant improvements in air flow and filtration while being washable and reusable. Why throw money away on a paper filter each time the old one gets dirty when you can upgrade to a serviceable AIRAID Premium Filter for often less than the cost of two stock replacements?
