This Banks Super - Scoop Air Intake is designed for 2011 - 2014 GM Duramax vehicles. It's an add - on to the Ram - Air Intake System. The Super - Scoop fits into the front bumper valance, pushing a large amount of cool, pressurized ram air into the air filter housing. Rainwater and debris are drained out from the bottom. By getting more air into your engine, there's more oxygen for burning fuel, leading to better and more efficient combustion and more power. The cold air box has a huge bottom opening and the optional Super - Scoop inlet to draw in cooler, denser air from outside the vehicle. Key features include increased power and MPG, optimized Ram - Air Intake efficiency, and improved fuel economy. It also reduces smoke and lowers exhaust gas temperatures. It's emissions compliant in 49 states and works with the 42220/42230 Banks Ram - Air Systems. Note that fender lining and bumper valance trimming are required for installation. Part Number: 42237.

Using this Banks Super - Scoop Air Intake is easy. First, make sure you have trimmed the fender lining and bumper valance as required. Then, install the Super - Scoop into the front bumper valance.

Also, make sure the drainage at the bottom is clear so that rainwater can flow out smoothly. If you notice any issues or have questions, don't hesitate to contact the manufacturer.
