Frequently Asked Questions

Will this fit my 2022+ Sportster S?

No — this part is for 1991-2021 Sportster models. The Sportster S requires a different intake system designed for the new platform.

Does this come with everything I need to install it?

Yes — the VO2 X includes the billet cover, velocity stack, air filter, and all ARP mounting hardware needed for bolt-on installation.

Can I clean and reuse the air filter?

Yes — the high-flow filter element is washable. Clean it periodically as part of routine maintenance rather than replacing it.

Do I need to retune my engine after installing this intake?

A fuel-air adjustment or ECU tune is recommended to optimize performance with the increased airflow, though the intake functions as a bolt-on without tuning.
