Ignition Coil and Iridium Spark Plugs for Volvo C30 (2007-2011) 2.4L

Direct-Fit Ignition Coil and Iridium Spark Plug Kit for 2007-2011 Volvo C30

Direct-Fit Ignition Overhaul: Restores factory spark energy, stabilizes idle, and eliminates ignition misfires across all five cylinders on naturally aspirated 2.4L Modular engines.

The Stock C30 Ignition Coil Heat Breakdown

The transversely mounted B5244S4 inline-5 traps significant thermal energy beneath the upper decorative cylinder cover. Over extended thermal cycles, the factory coil-on-plug boots develop micro-fissures and internal primary copper windings suffer dielectric breakdown. This insulation failure allows high-voltage arc-over directly to the cylinder head rather than across the spark gap, resulting in hesitation under load, P0300-P0305 misfire diagnostic codes, poor fuel economy, and potential catalyst damage.

The Engineering Solution

This complete 5-cylinder ignition refresh kit includes direct-fit coil assemblies paired with matched iridium spark plugs. Each coil-on-plug assembly is manufactured with high-density pure copper windings vacuum-potted in high-dielectric epoxy to withstand extreme engine bay heat and vibration. The fine-wire iridium center electrode plugs lower required ionization voltage, resist carbon fouling, and ensure consistent flame kernel propagation across the entire RPM band.
