When you’re building a highly modified performance car, there’s always plenty of fabricating to do. Many parts have to be “massaged” to get them to fit, even when they’re supposed to bolt right on! Isn’t it nice to know that at least one company has done the work for you? AEM has a complete line of Hybrid Air Intake systems for Hondas and Acuras with swapped engines. No need to buy a stock system for the car and try to get it to work with the engine or buy one for the engine and try to get it to work with the car. These systems are engineered for each engine/vehicle combination. And because AEM knows you’ve probably modified the engine internals, they’ve manufactured these systems using three-inch mandrel bent aircraft aluminum for maximum airflow. Like all AEM air intake systems, the AEM Hybrid Air Intake system is made in the USA and backed by a lifetime warranty.
Every AEM air intake system comes with the innovative, oil-free, high-flow AEM Dryflow air filter. Each Dryflow filter is engineered to exceed the normal flow capacities of the engine it is required for when clean, 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 filter is constructed of a unique non-woven polyester-based filter media supported by aluminum screen wire for rigid structural strength. 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. When it’s time to clean, simply tapping the filter a few times will 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 filter requires no oiling, so there’s never a chance of over-oiling. The Dryflow 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.
