      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.

        Air Filter

        I was skeptical about this item. After all, all it is is a filter. I purchased it, and must say did notice (not immediately) but very soon after a few days the better mpg and the more roar in the engine when accelerating. Its not supercharger roar but small improvement. Satisfy needless to say

        Excellent Fit Finish

        Not much to say about this product. The fit was fantastic, just as expected from a KandN product. Not much of a performance gain, if any, but that's not what these drop-in filters are really about. You get a reusable filter (no more $20 paper filters), with a bit more air flow and a touch more intake sound. Overall, a great value for 5 minutes work.

      Do you need to preoil this filter before install or can you pop it in straight from the package. This will be my first upgrade for Lil Red.
