Upgrade to Precision, High-Energy, and Tunable Crank-Fired Ignition

Tired of tinkering with the distributor, points, and condenser on your classic vehicle? We’ve got your solution!

The Megajolt/E from Autosport Labs is designed to work with the commonly available Ford EDIS 4,6 or 8 cylinder ignition module. Combined with inexpensive and easy to obtain OEM coil pack(s), trigger wheel and crank sensor, you can realize your engine’s potential at a fraction of the cost of other systems.

Please note: When ordering, specify load sensor type as either MAP (onboard) or TPS (not included). Trigger wheel and trigger sensor are not included
