Product Details

K&N Engineering is well-known for making high-flow air filters and intake systems that help engines breathe better. This FI Performance Air Intake System, part number 57-1137, is built to give your Harley-Davidson motorcycle a noticeable boost in performance. It replaces the stock air cleaner assembly, which can be quite restrictive, with a K&N high-flow filter and a cast aluminum intake tube designed for better airflow.

This setup is designed to increase horsepower by allowing your engine to take in more air. The system includes a die-cast aluminum throttle-body mounting plate and all the necessary hardware for installation. Beyond the performance gains, it also gives your Harley a more aggressive look. K&N intakes are CARB exempt and street legal in all 50 states, meaning they meet emissions standards for use on a wide range of Harley-Davidson Softail and Dyna models from 2001 through 2017, including popular bikes like the Fat Bob and Dyna Super Glide.
