Ignition Coil and Iridium Spark Plugs for Volvo XC90 (2011-2013) 2.5L

Direct-Replacement Ignition Kit for 2011-2013 Volvo XC90 2.5L

Restores direct secondary ignition voltage and combustion efficiency: This matched kit replaces aged factory coil-on-plug modules and worn spark plugs on the turbocharged inline-5 to eliminate misfires, rough idle, and unburned hydrocarbon emissions.

The Stock XC90 Thermal Breakdown and Secondary Voltage Drop

Mounted directly over the cylinder head within the tight engine bay of the P2 chassis, OEM coil packs on the B5254T engine suffer severe thermal degradation. Chronic heat cycles break down internal epoxy potting and degrade secondary copper windings, causing dielectric breakdown, micro-arcing, and intermittent primary signal loss under high boost. Concurrently, standard nickel or high-mileage electrodes widen their spark gap, overworking the coils and causing cylinder-specific misfires under heavy load.

The Engineering Solution

This comprehensive service kit includes 5 high-output coil packs and 5 fine-wire iridium spark plugs engineered to factory dwell profiles. Coils are built with high-grade copper windings and premium thermoplastic housings that resist dielectric punch-through under high thermal stress. The ultra-dense iridium electrode plugs offer exceptional erosion resistance, allowing a consistent gap, reduced voltage requirement, and complete flame front propagation across all 5 cylinders.
