Ignition Coil and Iridium Spark Plugs for Volvo V70 (2004-2007) 2.5L

Direct-Fit Ignition Coil and Iridium Spark Plug Kit for 2004-2007 Volvo V70

What it Does: Replaces degraded factory coil packs and worn spark plugs to eliminate misfires, restore clean combustion, and stabilize idle across all 5 cylinders.

The Stock V70 Secondary Ignition Degradation

Mounted directly atop the cylinder head within the enclosed P2 engine bay cover, factory Volvo coil packs endure extreme thermal cycling. Over time, internal epoxy insulation breaks down, causing secondary voltage leakage, micro-arcing, and intermittent misfires under turbo boost. Simultaneously, standard copper or platinum plugs suffer gap erosion from sustained high combustion temperatures, increasing electrical resistance and overworking the primary ignition circuit.

The Engineering Solution

This comprehensive tune-up kit features five coil-on-plug assemblies engineered with high-density copper primary and secondary windings, housed in heat-resistant thermoplastic to prevent dielectric breakdown. Matched with five fine-wire iridium spark plugs, this setup requires significantly lower firing voltage while maintaining exceptional spark stability and resistance to fouling. Precision blade terminals ensure zero-resistance contact with the OEM harness.
