PS40 Ignition Coil Black

The FAST Electronics PS40 Ignition Coil in Black (MPN 730-0050) is a direct-fire ignition component engineered for street and performance applications where reliable spark delivery is non-negotiable. Whether you're running a naturally aspirated engine, forced induction setup, or high-revving build, this coil pack handles the demanding electrical load required to ignite lean fuel mixtures and maintain consistent firing across the RPM band. Mechanics and tuners choose FAST ignition coils when OEM units fall short or when engine management upgrades demand precision spark control.

FAST Electronics builds this coil with durable construction designed to withstand heat cycling and electrical stress that standard components cannot tolerate. The compact, flat-black finish houses primary and secondary winding geometry optimized for fast rise time—the rate at which voltage climbs to ionize the spark plug gap. This rapid voltage ramp reduces dwell time demands on your ECU and allows for tighter ignition timing control, which translates to improved combustion efficiency and sharper throttle response across your powerband. The robust design minimizes electromagnetic interference, keeping your engine's electrical noise floor clean and your sensor readings accurate.

This coil excels in carbureted engines upgraded with capacitive discharge (CD) ignition systems, EFI conversions, and custom standalone engine management platforms. Installation requires proper coil-to-plug wire routing and solid primary circuit connections; verify your ignition system voltage and dwell timing with your ECU tuner or engine builder before installation. The PS40 pairs well with quality plug wires, hotter spark plugs, and optimized fuel maps to unlock full potential—a genuine upgrade that demands professional installation and tuning expertise to realize measurable gains in starting reliability and midrange torque delivery.
