Probably no engine is more sensitive to proper airflow and filtration than a diesel. Insufficient flow caused by restriction or a dirty filter can cause exhaust smoke and excessive emissions. Adding an AEM Brute Force HD Diesel Air Intake system to your diesel truck or SUV can ensure that you never encounter these problems. The system begins with an oil-free, high-flow Dryflow air filter that is engineered to dramatically out-flow the engine’s requirements and deliver excellent dust holding capacity. Compared to the standard nine-inch Brute Force Dryflow filter, the HD Diesel filter features over twice the filter media surface area and utilizes deep pleats to improve dust holding capacity and increase cleaning intervals. The filter is connected to a mandrel-bent, lightweight high-flow intake tube that delivers the intake air to the engine. The intake tube features high-strength dogbone brackets and dual rubber soft mounts, to ensure that the system lasts under heavy-duty operating conditions. AEM’s quality-first manufacturing processes enable it to offer the Brute Force HD Diesel Air Intake system with a lifetime warranty, and like all AEM air intake systems, it’s made in the USA.
All AEM Brute Force air intake systems come with the innovative, oil-free, high-flow AEM Dryflow Brute Force air filter. The Dryflow Brute Force air filter is engineered to exceed the normal flow capacities of large displacement engines, while providing outstanding filtration and dust holding capacity. And the flow requirements are exceeded by a wide margin, which allows you plenty of leeway for engine breathing modifications, without needing to worry about having enough intake airflow. The AEM Dryflow Brute Force filter is constructed of a unique non-woven polyester-based filter media supported by a lightweight mineral-reinforced plastic cage. This filter media doesn’t require oil to filter and trap dirt and contaminants, and actually sheds dirt under engine vibration, unlike cotton-gauze, which holds onto contaminants until you clean the filter. The plastic cage helps the filter retain its shape, eliminating the chance of the filter collapsing from flow demands. The Brute Force filter is a favorite of racing teams competing in rough, dusty conditions. Cleaning is easy; simply tap the filter a few times to remove most of the dirt from the filter pleats, then spray the filter with AEM’s environmentally friendly, mild, all-purpose cleaner. Rinse the filter with clean water and allow to dry, or blow dry with compressed air. Best of all, the Dryflow Brute Force filter requires no oiling, so there’s never a chance of over-oiling. The Dryflow Brute Force filter is extremely durable and will withstand almost unlimited cleanings.
John Concialdi and Bob Sullivan co founded AEM in 1987 as a tuning performance shop in Compton California. Both men had extensive technical backgrounds in engines and engine airflow, and in a short time AEM became the go-to company for performance modifications. By 1993, when the company relocated to Gardena California, it had become commonplace to see cars wearing the bright yellow AEM logo winning races. AEM tirelessly dyno tested and worked closely with racers and auto manufacturers in an effort to understand intake energy dynamics. This resulted in the sale of their first air intake kit in 1994. AEM can boast a number of firsts and unique products: They’re the first manufacturer to make an intake system with specific tube lengths and diameters to take advantage of pressure waves in the inlet tract; they developed the first dual chamber intake kit; they designed an air bypass valve to prevent hydro-lock should the air filter ingest water; and they created one of the first hybrid intake systems for modified cars. AEM continues to create innovative products to help you get more power from your car.
