Banks Power is a producer of aftermarket engine-power systems for pickup trucks, SUVs, and motorhomes. Since an engine can be thought of as an air pump, or lungs, of a vehicle, Banks' product line primarily deals with getting more oxygen into (and out of) an engine to increase efficiency, thereby creating more power. The company currently occupies four acres on the Banks campus in Azusa, California. A recent 7-acre acquisition in adjacent Irwindale will be developed to include expanded motorhome testing and installation facilities, and an overnight camping park for Banks customers.
