170-0566A Tuned induction air cleaner kit. Chrome

The S&S tuned induction air cleaner kit in chrome provides a significant performance boost for Milwaukee-Eight engines. This bolt-on kit replaces the restrictive stock intake with a high-flow 2:1 system featuring tuned-length runners. By utilizing air column inertia, the design creates dynamic pressure waves that force more air into the combustion chamber, increasing both torque and horsepower. It fits 2018–2024 Softail models, 2017–2025 Touring models, and 2017–2025 Trikes, though it will not fit models with fairing lower glove boxes or Twin Cooled engines. The kit includes cotton-based high-flow filters that offer over twice the surface area of the original equipment. For those riding in extreme rain or dust, pre-filters are available separately to protect the intake track.
