BD Diesel AFC spring kits help your truck run better under low boost. In some diesel trucks, an air-fuel control housing (AFC) is used to determine how much fuel is delivered to the engine under various conditions. If the spring in the AFC housing is too stiff, it will take an immense amount of boost to fully open, therefore limiting potential power output. These AFC spring kits are designed to fix that problem by replacing the stock, heavy spring with one that is lighter. The lighter spring allows the AFC to fully open under lower boost, giving you more fuel and more power
