Ignition Coil and Iridium Spark Plugs for Volvo S80 (2015-2016) 2.0L

Direct-Replacement Ignition Coil and Iridium Spark Plug Kit for 2015-2016 Volvo S80

What it Does: Replaces degraded factory coils and worn plugs to restore consistent high-voltage arc transfer, eliminate boost misfires, and stabilize idle across all combustion cycles.

The Stock S80 Coil Insulation Breakdown and Gap Erosion

The forced-induction 2.0L Drive-E engine operates under elevated cylinder pressures and tight packaging tolerances, subjecting coil boots and windings to extreme thermal soak in deep cylinder head wells. Over time, OEM secondary windings experience internal insulation breakdown and micro-fracturing from heat cycles, increasing internal electrical resistance. Simultaneously, ground electrodes degrade and spark gaps widen, forcing aging coils to operate beyond their dielectric limits. This results in weak spark energy, unburned fuel blow-by, hesitations under load, and trigger codes such as P0300 through P0304.

The Engineering Solution

This service-matched ignition kit pairs four coil-on-plug assemblies featuring pure copper primary and secondary windings encased in high-dielectric epoxy with four pre-gapped laser-welded iridium spark plugs. The copper core architecture delivers high spark energy retention under boost while resisting internal heat-related resistance creep. The fine-wire iridium center electrodes provide exceptional melting-point resistance against erosion, reducing coil secondary voltage demand. Direct-fit blade connectors and high-temperature silicone boots prevent flashover and ensure positive electrical continuity.
