aFe Magnum Force Stage 2 Air Intake Systems

aFe Magnum Force Stage 2 air intake systems outflow factory systems by over 30 percent, providing maximum gains of 16 hp and 26 lbs.-ft. of torque. These kits obtain such impressive gains by using CAD-designed and dyno-tuned intake tubes, and either of the two distinctly different types of filters included for your driving style. Both filters use 360 degree flow domes, but one is a 3-layer oil-free design, while the other is a 5-layer, pre-oiled, washable and reusable, high performance filter—each style provides maximum air flow. Give your vehicle better flow and a little kick with aFe Magnum Force Stage 2 air intake systems.

Aeromotive BoostWorx DualX ZL1 Universal Fuel Module Controllers

Aeromotive VaporWorx BoostWorx PWM controllers for DualX ZL1 universal applications simplify installation and increase overall fuel system performance for dual OEM ZL1 fuel module applications. DualX uses a progressive ramping strategy with connections on the controller for the primary (pump 1) and follower (pump 2). The follower pump runs at lower duty cycle than the primary, allowing the follower pump to be on at all times, but at a lower average power, and allowing the pumps in the follower module to continually fill the reservoir with fuel, so it is ready to feed the engine under the most challenging conditions. As the primary pump increases in duty cycle, so does the follower, and once the primary is at 100 percent, the follower continues to increase to 100 percent duty cycle, as needed. This strategy is automatic and requires no user programming or adjustments. BoostWorx PWM DualX ZL1 fuel module controllers feature: * Everything needed electrically to drive the fuel pump module -- No relays, Hobb's switches, or filters needed -- OEM fuel level sensor can be used if desired * Unmatched low fuel level capability * Up to a 2/3 reduction in power to the fuel module during idle and cruise vs. traditional systems * 80-amp minimum continuous power rating in a compact controller package * Over-temperature shutdown with automatic reset * Short circuit protection * OEM Delphi/Aptiv connections for terminals, seals, and connector bodies, where appropriate * All cross-linked polyethylene wiring * Single 20 ft. wiring harness to the fuel module * UL94 rated components used throughout * Integrates into the OE ECM to allow all safety systems to remain functional * Can be used in constant or manifold referenced fuel pressure modes -- Manifold referenced suggested to further reduce electrical demand
