Common questions
Will this intake runner fit my 2021 or newer Milwaukee-Eight Harley?
No, this S&S Cycle Intake Runner is specifically designed for 2017-2020 Milwaukee-Eight engines. Newer M8 models utilize a different intake geometry.
Do I need to get my bike tuned after installing this part?
While an intake runner alone might not always necessitate a full re-tune, any significant change to your bike's intake system, especially when combined with other performance parts, will benefit from a fuel map adjustment to optimize performance and prevent lean conditions. We recommend consulting with your preferred tuner.
Is this a difficult part to install for a home mechanic?
This S&S Cycle Intake Runner is a direct bolt-on replacement for the factory component. Basic mechanical skills and common hand tools are typically sufficient for installation, and no specialized machine work is required.
