63 Series intake systems are street legal in most states. However, they are not legal for use in California and other states adopting California emission standards.
K&N's AirCharger® Intake Systems are designed to get more horsepower from your sport ATV. These high flow air intake systems eliminate the OE airbox assembly and replace it with a K&N high flow air filter, roto molded polyethylene intake tube, and powder coated heat shield. These complete intake systems are designed to provide an increase in air flow and performance that can come in handy whether riding on the track, through the woods, or in the sand.
