About This Product
The K&N AirCharger performance air cleaner kit is a serious upgrade for Milwaukee-Eight owners looking for significant power gains. This kit features a polished cast aluminum 90-degree intake tube and a chrome-plated filter tip with the iconic K&N logo. On the dyno, this system has shown gains of up to 13 horsepower on 96-inch engines. It fits 2018 to 2024 Softail models, 2017 to 2025 Touring models, and 2017 to 2025 Trikes, though it excludes Twin Cooled models and those with fairing lowers. The kit includes the breather assembly and all necessary mounting hardware. It is a complete performance intake system designed to let your EFI-equipped Harley breathe deep and run stronger.
Manufacturer part number: 63-1138C.
