PS40 Ignition Coil Polished

The PS40 Ignition Coil Polished from FAST ELECTRONICS is a precision-engineered replacement coil designed for enthusiasts and mechanics who demand reliable spark delivery under high-load conditions. Whether you're running a street machine, weekend track car, or performance build, a quality ignition coil is the foundation of consistent combustion—directly affecting throttle response, fuel economy, and overall drivability. This coil replaces worn or failing OEM units that lose voltage efficiency over time, causing weak spark, misfires, and rough idle.

The PS40 Ignition Coil Polished features a polished finish that not only improves aesthetics under the hood but also aids in heat dissipation—critical for long-term reliability in modified or turbocharged applications. FAST ELECTRONICS coils are wound with high-quality copper and epoxy-sealed for moisture resistance, ensuring consistent 45,000+ volt output across the RPM range. The compact design (5.4 x 5.3 x 85 inches) allows straightforward installation in tight engine bays, while the 1.79 lb weight keeps rotating mass minimal. This coil maintains proper voltage saturation at high RPM, preventing the voltage drop that causes ignition issues in high-rev engines.

Mechanics and tuners working on classic hot rods, modern performance cars, and boosted platforms trust FAST ignition coils for their durability and consistent spark characteristics. Installation is straightforward—simply disconnect the old coil, unplug the connector, and swap in the PS40 without additional modifications. Verify your vehicle's original coil configuration before ordering to ensure proper fitment; compatibility varies by make, model, and year. This replacement coil pairs well with quality spark plug wire sets and fresh plugs as part of a complete tune-up, delivering noticeable improvements in cold-start behavior and mid-range throttle feel.
