    Brute Force HD Intakes are designed to deliver maximum flow, filtration, and durability for heavy-duty applications. They even outperform standard Brute Force Intakes in filter flow and dust-holding capacity.

    Available polished or powdercoated silver, Brute Force HD Intakes are made from lightweight aircraft aluminum. They include a bulletproof heat shield (powdercoated black), high-strength dogbone brackets, dual rubber soft mounts, and complete hardware kit.

    Brute Force HD Intakes incorporate AEM DryFlow Air Filters to provide longer life and higher efficiency for maximum performance in between maintenance. Filters have over twice the surface area with deep pleats to hold more dust and extend service intervals. DryFlow Filters do not use oil to trap dirt, which reduces cleaning time and stops oil from traveling up the inlet to foul sensors and void your vehicle's warranty.
