Ignition Coil & Iridium Spark Plugs for Volvo XC90 (2007-2014) 3.2L I6

Direct-Replacement Ignition Coil & Iridium Spark Plugs for 2007-2014 Volvo XC90

Restores proper ignition timing and combustion efficiency for the 3.2L SI6 engine. This comprehensive coil and iridium plug kit replaces degrading factory ignition components to resolve misfires, rough idling, and under-load hesitation.

The Stock XC90 Ignition Degradation

The original equipment ignition coils on the P2-chassis XC90 are subjected to extreme thermal cycling given their location directly above the B6324S cylinder head. Over 80,000 to 100,000 miles, the internal epoxy potting begins to micro-crack, allowing voltage to leak and arc to the engine block rather than reaching the spark plug gap. This degradation, compounded by standard electrode wear on the factory spark plugs, increases the required firing voltage. The resulting weak spark causes incomplete combustion, leading to noticeable hesitation under acceleration, unburnt fuel contaminating the catalytic converter, and eventual cylinder misfire codes (P0300 through P0306).

The Engineering Solution

This replacement kit addresses factory thermal vulnerabilities by utilizing upgraded internal coil windings and high-dielectric epoxy resin. These materials provide superior resistance to heat-soak and vibration-induced breakdown, ensuring a consistent high-voltage output even during extended high-load driving. The included iridium spark plugs feature a fine-wire center electrode and a laser-welded ground strap. Iridium's extremely high melting point (over 4,400°F) prevents electrode erosion, maintaining a precise spark gap over a significantly longer service life than standard copper or platinum plugs. Together, the robust coil housing and optimized spark plug metallurgy guarantee a concentrated spark for efficient fuel atomization, restoring factory throttle response, fuel economy, and emission compliance without the need for ECM reprogramming.
