Ignition Coil and Iridium Spark Plugs for Volvo C30 (2007-2013) 2.5L

Direct-Fit Ignition Coil & Iridium Spark Plug Kit for 2007-2013 Volvo C30 2.5L

Complete Ignition Service Kit: Direct-replacement coil-and-plug package engineered to eliminate cylinder misfires, rough idle, and spark blowout on the turbocharged 2.5L 5-cylinder engine.

The Stock C30 Thermal Degradation & Secondary Voltage Loss

The Volvo B5254T engine places its ignition coils directly over the cylinder head under a tight aesthetic shroud, subjecting them to continuous thermal cycling. Over time, heat soak degrades the internal epoxy and secondary copper windings, causing insulation breakdown, high-RPM misfires (DTC P0300–P0305), and sluggish boost onset. Simultaneously, worn factory spark plugs experience widened electrode gaps, forcing the aging coils to operate at excessive secondary voltages and accelerating electrical failure.

The Engineering Solution

This 5-cylinder overhaul kit features 5 high-output coil-on-plug assemblies built with premium-grade copper windings and durable dielectric housings to resist thermal fatigue. Paired with 5 fine-wire iridium spark plugs, the laser-welded center electrodes require lower firing voltages while resisting spark erosion under boost. Precision blade terminals and OEM-geometry boots ensure a weather-tight connection, consistent dwell timing, and crisp throttle response across the entire RPM band.
