      Description

      Improves Horsepower. When you're doing routine maintenance to your F-150 and you noticed the air filter is dirty, don't just replace it with another factory paper filter. Instead, replace your stock air filter with a new high flow Air Filter from K&N. This drop-in filter is designed to improve your 5.4L's performance by increasing the horsepower and acceleration, all while still providing excellent filtration.

      Filters Out Harmful Contaminants.
      The K&N Drop-in Air Filter filter's out harmful contaminants with it's unique layered design. K&N Air Filters are made up of layers of specially treated cotton gauze that are sandwiched between two epoxy-coated aluminum wire screens for durability. K&N uses a specially formulated grade of oil to treat the cotton gauze layers, which causes a tackiness throughout the cotton's microscopic strands creating a powerful filtering media that ensures engine protection.

      Washable and Reusable. This Replacement K&N Air Filter is designed to be washable and reusable, giving you up to 50,000 miles before needing to be cleaned out, dependent on driving conditions. Not only that, but the filter is backed by the K&N Million Mile Limited Warranty for added peace of mind.

      Drop-In Replacement. K&N designed this Air Filter to be a direct drop-in replacement for the stock air box. There is no cutting or trimming required for installation.

      Application. The K&N Replacement Air Filter is specially designed to fit all 2004 to 2008 F-150s powered by the 5.4L V8 engine.
