When you purchased an AEM Dryflow filter you made an investment in your car. Why not protect that investment with an AEM Pre-Filter wrap? The Pre-Filter is engineered to protect the filter under most driving conditions. Every Pre-Filter is treated with a proprietary water repellent to prevent splashes of water or mud from saturating the filter. The Pre-Filter is also your first line of defense when driving in harsh, dusty environments. The Pre-Filter traps small dirt particles, keeping much of the dirt from reaching the filter, thereby extending the length of time between necessary filter cleanings. Each AEM Pre-Filter is embossed with the AEM logo, and Pre-Filters are available for most Dryflow filters.30.99Brand: AEM Part Number: 1-4000 UPC: 024844263698
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.Product Reviews (1)
