2017 Harley-Davidson® 107CI FL Models Gain Power from the 63-1139 Intake
- 8 nov 2017
Performance The stock air intake on the 2017 Harley-Davidson® 107CI FL models restricts airflow. The 63-1139 performance air intake opens up the lungs on that big V-twin, and that increase in airflow adds the potential for a substantial performance boost. An example of the estimated power increase is revealed in the dyno charts that K&N’s testing showed when the 63-1139 was installed on an otherwise stock 2017 107CI Harley-Davidson Road Glide. The intake bumped up the Glide’s muscle by almost 3.5 estimated horsepower at just over 4400 RPM. Just as importantly, the intake unleashed an estimated 5 foot-pounds of torque at the acceleration sweet spot of approximately 3600 RPM.
Design and Style The forward-sweeping, cast aluminum high-performance intake tube cuts a mean and aggressive profile on the right side of the 2017 Harley FL models. The matte black finish is accented with a brushed aluminum K&N logo and raised horizontal ridges. That intake tube houses an internal velocity stack and innovative built-in breathers. The 63-1139 performance air intake is capped off with a K&N high-flow cotton gauze air filter. The exposed conical filter element leaves no doubt that your Harley is fitted with the ultimate in performance and protection.
The installation of the intake is a straight-forward process. When assisted by K&N’s clear and detailed instructions and basic hand tools, the installation takes about 90 minutes. That’s it. The occasional cleaning of the washable and reusable air filter element is a simple process using a kit like the K&N 99-5050. K&N’s engineers have made both the fitting and care of the 63-1139 a snap. Applications The 63-1139 performance air intake fits the Harley models in the list below.
