The RK Series of Air Intake Systems offers increased performance while maintaining a factory appearance. K&N's RK-3910-1 has a custom backing plate that fits onto the stock throttle body or carburetor. This backing plate is made from powder-coated aluminum and dyno-tuned to provide increased performance. This system also includes a tuned velocity stack to help direct airflow into the engine for better performance. Perhaps one of the nicest features of the RK-3910-1 intake system are the oil channels incorporated into the backing plate to direct crankcase vapor and oil from the breather bolts back into the engine.

K&N's RK-3910-1 is the high capacity version of the RK-3909-1 intake system. RK-3910-1 uses a K&N air filter that is 5/8 inches taller than the standard height air filter used in part number RK-3909-1. This translates into increased filtration capacity, longer service intervals, and a larger increase in estimated horsepower.

K&N dynamometer tests show an estimated increase of 10.76 horsepower and 10.85 lbft of torque at 5,206 RPM on a 2010 Harley-Davidson Fat Boy with a 96 cubic inch engine. Results will vary with other models.

Part number RK-3910-1 can be easily installed with basic hand tools in 90 minutes or less and is backed by the K&N Million Mile Limited Warranty®

K&N's RK Series Air Intake, part number RK-3910-1, fits most Twin-Cam Harley-Davidson models from 1999 to 2012, including 2008 to 2012 Softail models. For 2008 to 2012 Touring Model Harley-Davidson motorcycles use part number RK-3930. For 2008 to 2012 Dyna modes, see part number RK-3931. Air intake RK-3910-1 will fit the following vehicle applications:
