Ignition Coil and Iridium Spark Plugs for Volvo V70 (2005-2006) 2.4L

Direct-Fit Ignition Coil and Iridium Spark Plug Kit for 2005-2006 Volvo V70

What it Does: Delivers a complete 5-cylinder ignition overhaul to restore secondary voltage output, eliminate erratic idle, and prevent engine misfires under load.

The Stock V70 Ignition Breakdown

The Volvo P2 chassis positions the inline-5 ignition packs directly beneath the plastic engine valley cover, trapping severe radiant heat. Over time, continuous thermal cycling degrades the factory internal epoxy and secondary copper windings, causing dielectric breakdown, erratic spark voltage, and micro-cracking in the boots. This degradation results in cold-start stutter, hesitation under acceleration, and persistent P0300-P0305 diagnostic trouble codes.

The Engineering Solution

This direct-replacement ignition kit features five coil-on-plug packs paired with five fine-wire iridium spark plugs engineered to factory dwell parameters. Each coil assembly utilizes high-conductivity internal copper windings, thermal-resistant epoxy potting, and OEM-spec blade terminals for uninterrupted contact. The iridium spark plugs maintain stable gap tolerances and resist high-temperature electrode erosion, ensuring instant flame kernel development and dependable combustion across all cylinders.
