Msd Ignition Atomic 2 Efi Throttle Body Kit - Natural Finish

Unleash the power of your engine with the Atomic 2 EFI system from MSD, featuring four 100LB/HR Fuel Injectors that can support up to 650 HP naturally aspirated or 635 HP on forced induction applications. The Atomic 2 ECU introduces fuel map self-learning and ignition timing control, enhancing idle stability, drivability, and wide-open throttle horsepower. Specifically designed to fit on a 4150 intake manifold, it provides ample clearance for factory air cleaners.

The Atomic 2 EFI delivers the expected performance and drivability benefits of fuel injection, ensuring quick starts, smooth idle, and excellent throttle response. Supported by the ECU for ignition timing, the Atomic 2 becomes a winning combination. Initial timing setup is simplified through a compact handheld monitor, where answering a few engine-related questions kick-starts your journey.
