Banks Power Ram Super Scoop~ Duramax(2003-2007)

Banks' exclusive Super-Scoop is an add-on product to the Ram-Air Intake System. Super-Scoop connects below the front bumper, forcing a big charge of cool, pressurized ram air into the Ram-Air Intake's air filter housing. Because the air is drawn from outside the engine compartment, it has greater density and makes more power than the warmer engine air.
Super-Scoop's cooler, denser air also improves fuel economy, reduces smoke and lowers exhaust gas temperatures! Rainwater and debris are funneled out of the bottom.
