Advanced Flow Engineering provides much better air flow for your Hummer with either an air filter or a complete air intake system. The Stage 2 air intake systems come complete, and will remove all the stock air box and intake tube. This allow AFE to build a much larger replacement air intake box and intake tube for greater air flow and filtering capabilities.The AFE replacement filter is constructed to give the best engine protection and improve power and torque. The special pleat design gives the AFE filter more surface area than the stock or competitive performance filters, and this area increases flow, horsepower, torque and keeps the dirt out. Advanced Flow Engineering manufactures these filters with multiple layer oiled medical grade gauze. This gauze is combined with an aluminum wire mesh screen to give you the best in air filter technology and protection.
