"With the addition of the RK-3918, the RK-3928 and the RK-3908 there is an instant performance increase over the stock system," said K&N Powersports Business Manager Dennis Mahan. "The RK-3918 adds a custom look with the billet outer cover that is ball grooved. The RK-3928 is chrome plated with a flame design, and the RK-3908 is luster polished and chrome plated with a mirror finish."
The custom assemblies' overall size is greatly increased to allow more air flow improving acceleration and service intervals. "It's been tested, adjusted and tuned at K&N," said Mahan. "This K&N Assembly has a velocity stack in it to breathe better."
The K&N Replacement Filter (E-3017), which is included in this assembly, is designed to be cleaned at approximately 25,000 miles. K&N Motorcycle Filters are washable and reusable.
Installation is very easy and should take between 45 to 60 minutes from start to finish. Due to the high volume of air intake it may be necessary to remap the fuel management system for optimum performance.
For added protection in wet riding there is a K&N Air Filter Wrap (E-3016DK) Accessory available for the Custom Assembly.
