Ignition Coil & Iridium Spark Plugs for Cadillac SRX (2007-2016) 2.8L 3.0L 3.6L V6

Direct-Replacement Ignition Coil & Iridium Spark Plugs for 2007-2016 Cadillac SRX V6

Restores proper combustion and eliminates misfires: This complete ignition overhaul kit replaces degraded factory ignition coils and worn spark plugs to ensure optimal voltage transfer and consistent spark timing under heavy engine load.

The Stock SRX Ignition Weakness

The GM High Feature V6 (LY7 and LFX variants) found in the SRX generates substantial under-hood temperatures due to tight packaging constraints. Over time, this intense heat cycling degrades the epoxy resin and primary/secondary windings within the OEM ignition coils, causing increased electrical resistance and dielectric breakdown. Simultaneously, standard factory spark plug electrodes erode from millions of combustion cycles, widening the precise spark gap. This mechanical and electrical degradation manifests as rough idling, poor fuel economy, hesitation during acceleration, and persistent P0300-series misfire codes triggered by weak or inconsistent spark delivery.

The Engineering Solution

This comprehensive kit addresses these thermal and electrical vulnerabilities by utilizing advanced materials for maximum reliability. The upgraded ignition coils feature high-grade silicone boots that resist heat soak up to 500°F, effectively preventing high-voltage arcing to the cylinder head. Internally, enhanced copper wiring ratios in the secondary windings ensure a higher, more stable energy output to bridge the plug gap even under peak cylinder pressures. Paired with fine-wire iridium center electrode spark plugs, this setup requires less firing voltage while providing a concentrated, hotter spark front. The ultra-durable iridium alloy stops gap erosion, guaranteeing complete fuel atomization and smooth power delivery.
