Vance & Hines has been building motorcycle exhaust since 1979 and has run factory-backed drag and King of the Baggers programs that feed straight back into its street products. Systems like the Torquer and the 2-into-1 designs are engineered around real dyno work, not just sound — which is why they show up on so many tuned Milwaukee-Eight and Twin Cam builds.
The Vance & Hines VO2 X Air Intake is engineered to uncork the performance potential of your Milwaukee-Eight Fat Boy. This high-flow intake system is designed to maximize airflow, delivering measurable horsepower and torque gains over the restrictive stock unit.

Common questions
Will this VO2 X Air Intake fit my 2017 or 2021+ Fat Boy?
No, this Vance & Hines VO2 X Air Intake is specifically engineered for 2018-2020 Harley-Davidson Fat Boy models. Other model years will require a different part number to ensure correct fitment.
Does the K&N filter element require maintenance?
Yes, the washable K&N filter element should be inspected and cleaned periodically, typically every 50,000 miles or if it appears visibly dirty. It should then be re-oiled using K&N filter oil.
Do I need a fuel tune after installing this air intake?
While some riders install air intakes without a tune, for optimal performance, throttle response, and to ensure proper air/fuel mixture, we highly recommend a fuel management tuner or an ECM flash after installing any high-flow air intake.
