MSD 8142 Pro Mag 44 Amp Ignition Coil Red Magneto Drag Race

The MSD 8142 Pro Mag 44 Amp Ignition Coil is a purpose-built, high-output coil engineered specifically for use with the MSD Pro Mag 44 magneto ignition system. Designed for pro-level drag racing applications including nitro-burning Top Fuel and Funny Car competitors, this coil delivers the extreme voltage and current capacity required to ignite nitromethane fuel under massive cylinder pressures.

At its core, this coil is wound with over a pound of high-quality copper wire around a molded DuPont Rynite core, allowing it to handle the full 44 amps of primary current output from the Pro Mag 44 magneto. The stepped-up output reaches 45,000 volts, sending over one amp of current across the spark plug gap — the kind of firepower needed to reliably ignite nitro fuel and withstand extreme boost pressures. For durability in the brutally demanding environment of drag racing, all internal windings are fully encapsulated in rugged epoxy for maximum vibration resistance and long-term reliability.
