Great filter. Fits perfectly and allows my truck to breathe much better than before. I've had K&N filters in all my vehicles and will continue to do so.

Best quality on market, I’ve bought many for various vehicles. This one is for my 2002 Dodge Cummins. Best filtering and noticeable power and mileage increase. Fast shipping and great service.
