Ignition Coils & Spark Plugs for Ford Mustang (2000-2004) 4.6L

High-Output Ignition Coils & Spark Plugs for 2000-2004 Ford Mustang (Modular V8 / SN95)

What it Does: Replaces factory Motorcraft coil packs and worn spark plugs with high-output equivalents to restore reliable spark energy, correct misfires, and improve fuel burn efficiency in the 4.6L V8 engine.

The Stock Mustang Ignition Shortcomings

The 4.6L Modular V8 engine relies on a coil-on-plug (COP) architecture that is notorious for heat-induced degradation over thousands of thermal cycles. Placed directly atop the cylinder heads, the factory OEM coils (such as the ubiquitous DG508) suffer from internal epoxy cracking and secondary winding resistance shifts. This degradation leads to weak spark propagation, hesitation under heavy engine load, cylinder misfires (commonly throwing P0300-P0308 diagnostic trouble codes), and unburnt fuel entering the exhaust stream. Ultimately, these thermal breakdowns rob the New Edge Mustang of low-end torque and smooth idle characteristics.

The Engineering Solution

This comprehensive ignition kit provides an immediate mechanical correction to the SN95's voltage delivery system by overhauling all eight coils and spark plugs. The upgraded ignition coils utilize high-grade silicone boots to seal out moisture and withstand extreme engine bay heat soak, preventing voltage leaks and carbon tracking. Inside the housings, enhanced primary and secondary copper windings generate increased spark voltage and extended duration. When paired with the included performance spark plugs, this coil set maximizes air-fuel combustion dynamics. The result is restored factory power output, a stabilized idle, superior throttle response, and consistent torque delivery throughout the RPM range without risk of high-RPM spark blowout.
