Ignition Coil and Iridium Spark Plugs for Chrysler LHS (1999-2001) 3.5L

Direct-Replacement Ignition Coil and Iridium Spark Plug Kit for 1999-2001 Chrysler LHS

What it Does: The ignition coil and iridium spark plug kit replaces aged factory coil packs and eroded plugs on the 1999-2001 Chrysler LHS to eliminate misfires, stabilize idle RPM, and restore complete combustion efficiency.

The Stock Chrysler LHS Ignition Breakdown

Mounted directly down in the deep plug wells of the 3.5L EGG V6 cylinder heads, factory ignition coils endure continuous thermal soak and severe heat cycling. Over time, the stock epoxy potting and internal copper windings suffer dielectric degradation. This allows secondary voltage to arc through the degraded boots directly to the cylinder head walls rather than firing across the plug gap. The result is secondary ignition failure, rough acceleration, unburned fuel dumping into catalytic converters, and persistent P0300-P0306 diagnostic trouble codes under load.

The Engineering Solution

This comprehensive ignition service kit pairs six reinforced pencil coils with ultra-durable fine-wire iridium spark plugs. The direct-fit replacement coils utilize heavy-duty copper primary and secondary windings encased in heat-stabilized thermoplastic housings to prevent internal electrical shorts. Complementing the coils, the 0.6mm laser-welded iridium electrode spark plugs drastically reduce the required ionization strike voltage, lowering thermal and electrical strain on the ignition coil drivers while preventing spark blowout. High-grade silicone boots provide superior dielectric isolation across factory spark plug tubes to eliminate voltage tracking completely.
