Ignition Coil & Iridium Spark Plugs for Volvo S80 (2007-2015) 3.0L 3.2L I6

Direct-Replacement Ignition Coil & Iridium Spark Plugs for 2007-2015 Volvo S80

Restores lost power, resolves persistent misfire codes, and ensures complete combustion for the P3 Volvo S80 inline-6 engines.

The Stock S80 Ignition Breakdown

The transverse-mounted SI6 engine layout in the P3 chassis generates significant heat soak, specifically near the firewall where the ignition coils are subjected to intense thermal cycling. Over time, the factory coil potting compound degrades and cracks, leading to internal arcing, increased primary resistance, and critical voltage drops. This thermal breakdown results in high-rpm quenching, rough idling, hesitation under heavy load, and the triggering of persistent P0300-P0306 cylinder misfire codes.

The Engineering Solution

This ignition replacement kit rectifies factory shortcomings by utilizing coils constructed with a high-dielectric epoxy and upgraded copper windings. This ensures consistent voltage output and superior resistance to high-temperature engine bay degradation. Paired with matched iridium-tipped spark plugs, this system guarantees a highly focused, stable spark arc. The ultra-fine iridium center electrode resists erosion under the B6304T’s turbocharged cylinder pressures, lowering the required firing voltage while virtually eliminating spark blowout during peak boost situations.
