Ignition Coil and Iridium Spark Plugs for Chrysler Sebring (2007-2010) 3.5L

Direct-Fit Ignition Coil and Iridium Spark Plug Kit for 2007-2010 Chrysler Sebring

Restore complete primary and secondary ignition efficiency: Replaces degraded factory coils and worn plugs to eliminate cylinder misfires, restore lost combustion pressure, and smooth out idle stability across the entire powerband.

The Stock Sebring Coil-on-Plug Degradation

Underhood thermal soak within the JS chassis engine bay subjects factory coil boots and primary/secondary windings to extreme continuous heat cycling. Over time, OEM insulation undergoes dielectric breakdown, creating micro-fractures, secondary arcing, and carbon tracking along the plug insulator. When combined with increased gap resistance from eroded stock plugs, the factory system demands higher secondary voltage than aged coils can provide, causing hesitation under load, unburnt fuel wash, and P0300-series misfire trouble codes.

The Engineering Solution

This direct-replacement kit features six heavy-duty coil-on-plug assemblies constructed with high-grade internal copper windings and sealed with high-dielectric epoxy to resist heat cracking and moisture penetration. Paired with laser-welded, fine-wire iridium spark plugs, the assembly lowers the required ignition firing voltage, resists spark erosion, and produces a faster, hotter flame kernel for optimal combustion stability and throttle response.
