Frequently Asked Questions

Does this require a fuel tuner or ECU reflash?

Consult your tuner — many riders pair air intake upgrades with fuel mapping to maximize gains. Stock jetting may work but tuning optimizes performance.

Is the air filter washable?

Yes — the high-capacity filter element is washable and reusable, reducing long-term maintenance costs.

What finishes are available?

Chrome, Black, and Black Contrast options are available to match your bike's aesthetic.

Will this fit my 2022+ Sportster S?

This part is for 1991-2021 Sportster models. Sportster S (2022+) uses a different intake design — check Vance & Hines for the correct model number.
