Twin Cam Harley Davidson Motorcycle Crowd Gets More Performance from K&N

     Printer Image
 
The Harley Davidson steps out with authority on the highway, with a v-twin engine that has always been its heart and soul. "K&N Engineering has been a market leader with the Harley Davidson crowd since the first development of a high-flow filter for the brand," said K&N Powersports Brand Manager Johnny Jump. K&N provides significant increases in airflow while optimizing service intervals from a washable re-usable filter. The K&N Filter has proven K&N's value, time and time again.

The RK-Series of Filters put K&N on the map in terms of optimizing horsepower from a production based intake assembly. The RK-3910-1, a Large Capacity, Custom Assembly for Twin Cam Harley Davidson motorcycles is no different. "It has been developed around an oversized K&N High-Flow Air Filter," said Jump. "This assembly (RK-3910-1) boosts performance, service intervals and filtration."

K&N Engineering designed the RK-3910-1 with a powder coated, billet aluminum backing plate, eliminating the external breathers. K&N eliminates the external breathers and makes them internal. This vents the vapors from the crank case into the intake air stream for a nice clean installation. This assembly features a bolted-in, dyno-tuned velocity stack and internal run breathers. The latest edition is designed to get more horsepower and retain the stock appearance for 1999 through 2012 Twin Cam Harley-Davidson Motorcycles. "The custom assembly keeps that factory appearance by utilizing the stock air cleaner cover," said Jump. "The laser etched K&N high-flow insignia sets it apart from the crowd."

"This K&N Kit (RK-3910-1) has a taller air filter for the Harley customers who bore and stroke their motors," said Dennis Mahan, K&N Powersports Business Manager. "If they want more performance they have to have more air. We made this kit specifically for the hopped up bikes and it allows Harley owners to get more air with this taller K&N Filter."

As with all K&N High-Flow Air Filters, the RK-Series Air Filters can be cleaned, re-used and is backed by the famous K&N Million Mile Limited Warranty.

At this time the RK-Series Air Filter Assembly (RK-3910-1) does not fit Twin Cam Engines with the Magnetti-Morelli fuel injection system. The Magnetti-Morelli systems have an oval port and the K&N Kit fits a round port.
