K&N XStream Top Universal Air Filters take performance to the next level with the addition of a filter within the filter's top adding more filter area for higher air flow and a longer service interval. The XStream Air Filter provides awesome air flow and outstanding filtration. When racing, in any environment, racers need all the protection and airflow they can get. K&N delivers. All K&N universal air filters are constructed with ultra-strong molded pliable rubber flanges which absorb vibration and allow for secure attachment and can also be stretched for up to 1/16 inch (1.5mm) to fit in-between sizes. K&N universal air filters are washable and reusable.

  Reduces intake noise and keeps particles and bugs out of the crevasses which significantly reduces your cleaning efforts. I've owned four of these systems on various cars and wouldn't operate without a filter wrap.

  Great Product!

  Works awesome ..without it my car kept sucking up water and killed the motor.

  Weather in Seattle can be unpredicable, one hour it's beautiful then the next its a heavy down pour. Having the filter wrap around my K&N filter sure did what it was suppose to do and its repelling water. I have a CAI on my Acura Integra. I would fully recommend purchasing this product along with your K&N air filter!! I am definitely buying one for my truck when I have the money!!

  Ordering process was very easy. Item arrived quickly. Fit was perfect. Tight enough it won't come off but still easy to install.
