Ignition Coil and Iridium Spark Plugs for Volvo S90 (2017-2019) 2.0L

Direct-Fit Ignition Coil & Iridium Spark Plug Kit for 2017-2019 Volvo S90

Primary Function: Restores factory secondary ignition output and combustion efficiency across all four cylinders to eliminate high-boost misfires, erratic idle, and hesitation.

The Stock S90 Thermal Breakdown Weakness

Volvo's 2.0L Drive-E forced-induction architecture generates intense cylinder head temperatures. Over extended service intervals, the compact factory coil boots and internal winding epoxy suffer from thermal fatigue, leading to dielectric breakdown and secondary voltage leakage. Combined with gap erosion on worn direct-injection spark plugs, this degradation manifests as cold-start misfires, sluggish throttle response, and unmetered fuel trim drift under boost.

The Engineering Solution

This comprehensive ignition service kit utilizes four reinforced coil-on-plug assemblies featuring high-conductivity copper windings insulated with premium epoxy resin to prevent arching and heat soak breakdown. Paired with laser-welded fine-wire iridium spark plugs (ILKAR8H6 profile), the package guarantees a stable, highly concentrated spark kernel capable of withstanding extreme cylinder pressures in both turbocharged (T5) and twin-charged (T6) configurations.
