Zylstra Automotive was founded in 1981 by John Zylstra, where they do repairs on all makes and models of vehicles. At this time the automotive computer era was just starting to boom. In 1997 Ford came out with its Powerstroke and the computer system on this engine. This computer system fascinated John and gave him the push to start installing performance products and fuel tanks. But he was not satisfied with the quality of the options that were out on the market for the auxiliary fuel and toolbox systems. In 2004 John started The Fuelbox, where he started to build his own design of auxiliary fuel and toolbox systems. Z4 Manufacturing provides you with many options of fuel boxes and has also designed its own Auto Fuel Control system. Z4 Manufacturing Inc. number one goal is to have the highest quality product and to have the best innovations.
