/ 01 · OVERVIEW

The HM B58 High Flow Intake with Heat Shield is built for owners who want a cleaner sound, better airflow, and a more responsive B58 without unnecessary bulk. This system replaces the restrictive factory setup with a high flow design that feeds the turbo a consistent supply of cool air while maintaining proper shielding from under-hood heat.

The included heat shield isolates the filter from rising engine temperatures, reducing heat soak and helping the car hold power more consistently in real driving conditions. With a direct fit layout for the G42 M240, G20 M340, and G22 M440, installation is straightforward and requires no cutting or modification.

Constructed from quality materials and designed around smooth airflow, the HM High Flow Intake delivers sharper throttle response, improved efficiency, and a clean, refined induction sound. No check engine lights and backed by a lifetime warranty.
