Ignition Coils & Spark Plugs for Lincoln Town Car (1998-2007) 4.6L

High-Output Ignition Coils & Spark Plugs for 1998-2007 Lincoln Town Car (Modular V8 / Panther Platform)

What it Does: This direct-replacement ignition coil and spark plug kit resolves common engine misfires and restores optimal fuel combustion in the 4.6L Modular V8.

The Stock Town Car Ignition Weakness

The OEM Ford/Lincoln coil-on-plug (COP) system on the 4.6L 2-valve Modular V8 is notoriously prone to thermal degradation over high mileage. Seated deeply within the cylinder head valley, the coils are subjected to intense, sustained heat soak. Over time, the factory epoxy degrades and develops micro-cracks in the coil housing. This allows moisture ingress—often from intake manifold coolant crossover leaks or simple condensation—resulting in secondary voltage shorts. The immediate symptoms are a flashing check engine light, prominent under-load misfires (especially when shifting into overdrive), a rough idle, and significantly compromised fuel economy.

The Engineering Solution

This upgraded set of 8 ignition coils and 8 performance spark plugs mitigates these localized thermal issues to restore factory drivability. The replacement coils feature high-temperature epoxy potting and upgraded heavy-gauge copper wire windings to optimize secondary voltage output and resist premature breakdown. High-grade silicone boots provide a superior dielectric seal against moisture and oil intrusion down the deep spark plug tubes. Paired with properly gapped performance spark plugs designed for an efficient burn, this kit ensures stable idle vacuum, increased horsepower retention, and a far more reliable ignition strike under maximum engine load.
