Engine & Fuel Management Systems
On late-model OE vehicles, fuel and spark are controlled by engine and fuel management systems. These systems optimize fuel efficiency, power, performance, as well as reduce emissions. Upgrading your carbureted engine with electronic fuel injection will modernize its power and performance as well as increase reliability. JEGS offers aftermarket engine management systems for sale on the market from well-known brands like Holley, FiTech, FAST, Chevrolet Performance, and others. Browse our full line of engine and fuel management systems that will help you complete your next engine project on your car, truck, or race vehicle.
