GMC 2500 Performance Air Intake by Banks Power – Ram-Air (2011–2012). Purpose-built for the 6.6L Duramax LML, this enclosed cold-air system increases airflow to support stronger performance while maintaining dependable filtration.
Engineered through CAD modeling, flow simulations, bench testing, and on-vehicle validation, the Banks Ram-Air is up to 35% less restrictive than stock. Its enclosed housing pulls in cooler outside air, helping lower exhaust gas temps and soot. The exclusive 5-inch bellows accommodates engine movement to protect components and extend service life. Available with oiled or dry filter elements, designed to avoid fault codes, and backed by a 5-year limited warranty. On tested applications, gains of up to +39 hp and +69 lb-ft have been recorded.
