PS40 Ignition Coil Black

The FAST Electronics PS40 Ignition Coil in Black (MPN 730-0050) is a high-performance oil-filled canister ignition coil engineered for reliable spark generation in demanding ignition systems. With a 0.400-ohm resistance specification and female socket configuration, this coil delivers consistent primary voltage conversion essential for precision engine performance in automotive and powersports applications.

The oil-filled design provides superior thermal management and electrical insulation, protecting against voltage leakage and maintaining stable secondary coil output across a wide operating temperature range. The 0.400-ohm primary resistance is critical for matching modern ignition module specifications—undersized or oversized resistance creates timing variance and misfire conditions. The female socket connector ensures secure seating with corresponding ignition harnesses, eliminating connection-related misfires common in loose or corroded factory connectors.

Users rebuilding classic vehicles, tuning high-performance engines, or replacing failed OEM coils rely on verified ignition coil specifications to avoid compounding electrical problems. The black powder-coat finish resists corrosion in underhood environments where salt air, heat cycling, and engine bay moisture accelerate oxidation. Weighing 1.81 lbs with compact dimensions (5.45 x 5.45 x 7.85 inches), the PS40 fits standard mounting locations without modification.

FAST Electronics is known for precision ignition and fuel system components used in restoration and motorsports builds where marginal ignition coils cause chronic starting, hesitation, and lean-condition damage. This PS40 replacement unit supplies OEM-equivalent spark delivery for troubleshooting distributor-based ignition systems and standalone ignition modules that demand exact impedance matching.
