GMC Sierra 3500 HD Performance Air Intake - AEM Induction - Brute Force HD + Dryflow Filter - `11-`12. This AEM Brute Force HD intake replaces the restrictive factory air box and filter with a high-flow, washable Dryflow element and engineered intake tube to improve throttle response and overall engine breathing.

Designed and dyno-tested for GM heavy-duty applications, this system routes air through an extra-large Dryflow synthetic filter housed in a replacement AEM logo-embossed air box to help lower intake temperatures and support increased performance. The tapered, oil-free Dryflow media is washable and reusable, and can extend service intervals under normal driving conditions. Intake tubing is molded polyethylene built for durability and aerodynamic flow. The kit is developed to retain factory emissions components such as the mass air flow sensor and is straightforward to install using common tools. AEM backs this product with a Lifetime Limited Warranty; note that some AEM intakes have varying legal status by state—verify vehicle applications for 50-state legality.
