The big “deep breathing” engine in your truck, SUV or muscle car needs an AEM Brute Force Air Intake system to unleash all of its power. AEM tunes the resonance properties of each vehicle’s system to deliver the maximum amount of air to the engine air inlet. Temperature testing is performed to determine the optimal location for the Dryflow air filter, to achieve the lowest air inlet temperature possible. Most systems also include a powder coated steel heat shield to shroud the filter from engine heat and road dirt. As a result, AEM’s Brute Force Air Intake system delivers more torque and horsepower, while at the same time providing critical air filtration that is so important for long engine life. AEM’s quality-first manufacturing processes enable it to offer the Brute Force 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.

AEM® 21-8018DP - Brute Force Polished Intake System
I received this product in a very timely manner. I, who am mechanically inclined but not a mdechanic, was able to install this product in much less time than manufacturer estimated and with much more ease than I would have expected. It is sturdy and secure. I'll add that I recently had a cat back dual exhaust system installed on this truck. The benefits that were achieved through this Brute Force Air Intake System and the combination of the new exhaust are absolutely phenomenal. I Would never have thought I could get such great performance from a 5-cylinder motor. Thank You AEM. I no longer want to get out of my truck. Brian M. Harbeson, DE.
