It's all about airflow. That's been the unofficial slogan at Gale Banks Engineering since day one. Airflow is power. The more air you flow through your engine, the more oxygen that is available for burning fuel. That means greater, more efficient combustion, and more power. How do you get more oxygen to the engine? You need to remove airflow restrictions, and if the air is as cool as possible, so much the better: colder air is denser and more oxygen-rich.
The stock system is highly restrictive; the cramped outlet has tight bends, the filter design is inefficient with minimal filtering area, and the air that it does draw in is warmer and less dense. The Gale Banks Engineering Ram-Air Intake System is "clean-sheet" engineered to minimize restriction, maximize flow and filter area, and draw cooler, denser air from outside the engine compartment.
The Gale Banks Engineering GMC Sierra Ram-Air Intake System delivers exceptional airflow and air density. Its large cotton gauze air filter requires fewer cleanings than competitive filters. With its giant 7-1/8" outlet, streamlined components and enclosed cold-air box that keeps hot engine air out of the intake, the ram-air flows up to 57% better than stock and up to 23% better than competitors.
In addition to greater power, you'll enjoy improved fuel economy, lower exhaust gas temps, and reduced black smoke. Also, Gale Banks Engineering’s unique 4-1/2" bellows accommodates engine movement, which prevents component damage and prolongs service life. This Gale Banks Engineering GMC Sierra Ram-Air Intake is backed by a 5-year warranty.
