APR High Flow Intake Filters are a direct upgrade to your factory intake system! Typically your engine is equipped with a cheap, mass-produced and restrictive paper filter system that must be replaced several times in the life of the vehicle. The APR Filter uses a proprietary, high-flow, cotton-gauze filtration material that is washable and will likely outlive the vehicle itself! The filtration material was flow-bench optimized to provide maximum performance while also providing excellent filtration that will keep your engine running clean for hundreds of thousands of miles with normal maintenance. With multiple decades of creating and selling high-flow filters for hundreds of thousands of vehicles with our upgraded intake systems, we're confident our line of drop-in filters will be an excellent upgrade for our budget-minded consumers!
