Edelbrock Performer nitrous systems are designed for a variety of engines. They're available in both wet and dry styles, and are adjustable for power increases of 50, 75, or 100 HP. Carbureted engines use a 1/2 in. aluminum spray-bar plate that fits between the carburetor and intake manifold. On fuel injection engines, nitrous is delivered via the air intake tube. Performer nitrous systems come complete with the nitrous bottle (empty), solenoids, switches, stainless braided hose, jets, nitrous and fuel filters, fittings, and mounting hardware.
