AEM Brute Force HD Intake SystemBrute Force HD air intakes for diesel applications feature a massive DRYFLOW air filter element! AEM Brute Force HD intakes are available for popular late model Cummins, Duramax and Power Stroke diesel engines. AEM engineers the Brute Force HD intakes to deliver maximum flow, filtration and durability for heavy duty applications and they even outperform the AEM BRUTE FORCE intakes for these vehicles in both dust holding capacity and filter flow. AEM's reusable DRYFLOW air filter for diesel applications is huge. Compared to the standard 9" Brute Force Dryflow Filter, the Brute Force HD Dryflow filter features over twice the surface area of filter media and utilizes deep, bull-nosed pleats to improve dust holding capacity and increase intervals between cleanings. The DRYFLOW air filter does not use oil to trap dirt so it takes the guesswork out of servicing your filter. AEM manufactures its BruteForce HD intakes from mandrel-bent, lightweight aluminum with high-strength dogbone brackets and dual rubber soft mounts for maximum durability, and includes a heat shield (when applicable) with a powder coated black finish, a complete hardware kit and comprehensive photo installation instructions. Brute Force HD intakes are available with a gunmetal powdercoat or mirror-polished finish.
