Ignition Coil & Iridium Spark Plugs for Pontiac G5 (2007-2010) 2.2L 2.4L I4

Direct-Replacement Ignition Coil & Iridium Spark Plugs for 2007-2010 Pontiac G5 (Ecotec 2.2L/2.4L)

What it Does: This complete ignition coil and iridium spark plug kit replaces degrading factory components to restore spark intensity, resolve misfire conditions, and optimize combustion efficiency.

The Stock G5 Ignition Shortcomings

Over time, the OEM ignition coils on the Ecotec 2.2L and 2.4L engines suffer from extreme thermal cycling and internal winding degradation. The factory coil boots dry rot due to persistent engine bay heat soak, leading to parasitic voltage leaks and ground arc-overs. Combined with worn factory spark plugs, this results in progressively weaker spark energy. Drivers typically experience rough idling, hesitation under heavy throttle loads, increased fuel consumption, and recurring P0300-series misfire diagnostic trouble codes that disrupt daily drivability.

The Engineering Solution

This comprehensive ignition overhaul addresses these specific Ecotec failure points. The included direct-fit ignition coils utilize high-grade dielectric epoxy and reinforced primary and secondary copper windings, maximizing voltage output to the spark plugs while actively resisting high-RPM thermal breakdown. Paired with performance iridium spark plugs featuring an ultra-fine center electrode, the system delivers a highly concentrated, consistent spark footprint. Iridium’s superior high melting point ensures long-term electrode integrity, translating directly to crisp throttle response, stabilized idle vacuum, and a much more complete fuel burn during the entire combustion cycle.
