Upgrade your 2011–2016 Duramax LML with the Banks Power Ram-Air Cold Air Intake System, engineered to deliver increased airflow, improved throttle response, lower exhaust gas temperatures, and better overall engine performance. The Banks Ram-Air system features a fully enclosed cold air box that prevents hot engine air from entering the intake, allowing cooler, denser air to reach the turbo for maximum efficiency and power.
Designed and tested by Banks Power, this intake system outflows the factory intake by up to 35%, helping improve horsepower, torque, and fuel economy while reducing exhaust gas temperatures. The system includes a large high-flow air filter, streamlined intake tube, and durable components designed for long service life and consistent performance.
Banks Ram-Air Intake Systems are available with either a dry or oiled filter depending on your driving conditions and maintenance preference. All systems are direct bolt-on installations and require no tuning, making them a simple and effective performance upgrade for your Duramax.

The 6 Intake Options (Why There Are 6)
They are basically split by:
- 2011–2012
- 2013–2014
- 2015–2016
- Dry filter version
- Oiled filter version
- Super Scoop compatible version
So the intake itself is basically the same Ram-Air system, just different year ranges + filter type.
