Ignition Coil & Iridium Spark Plugs for Chevrolet Captiva Sport Equinox (2008-2017) 3.0L 3.6L V6

High-Voltage Ignition Coil & Iridium Spark Plugs for 2008-2017 Chevrolet Captiva (LFX / Theta Platform)

Restores proper combustion and eliminates misfires: This complete ignition kit replaces worn factory coils and fouled plugs to ensure optimal voltage transfer and reliable starts for the 3.0L and 3.6L High Feature V6 engines.

The Stock Captiva Ignition Degradation

The factory ignition coils and standard plugs found on the 3.0L and 3.6L High Feature V6 are highly susceptible to thermal breakdown over extended mileage cycles. Positioned tightly against the firewall and beneath the intake manifold, these components endure severe, localized heat soak. Over time, the constant thermal cycling degrades the dielectric epoxy potting inside the coil packs, leading to internal micro-arcing and a significant drop in voltage output. Simultaneously, standard OEM spark plug electrodes wear down, widening the plug gap. This combined degradation forces the coils to overwork in order to jump the wider gap, resulting in hesitation under load, poor fuel economy, rough idling, and inevitable P0300-series misfire codes.

The Engineering Solution

This comprehensive ignition overhaul addresses these thermal and electrical vulnerabilities by pairing high-output ignition coils with premium iridium spark plugs. The upgraded coil packs feature enhanced primary and secondary copper windings, fully insulated by a high-temperature dielectric epoxy that resists heat soak and prevents high-voltage leaks to the cylinder head. This ensures a consistent, high-energy spark reaches the combustion chamber even under extreme operating temperatures. The included iridium spark plugs utilize an ultra-fine wire center electrode, which drastically lowers the voltage required to bridge the gap while providing exceptional resistance to electrical wear and chemical erosion. Together, this kit stabilizes the ignition curve, ensures a complete and efficient fuel burn, prevents unburnt hydrocarbons from fouling the catalytic converters, and restores smooth factory throttle response.
