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.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis 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.\u003c\/p\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable width=\"100%\" style=\"border-collapse: collapse; border: 1px solid #e0e0e0; font-size: 14px;\"\u003e\n  \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eFitment\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e2007-2010 Pontiac G5\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eEngine \/ Chassis\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003eEcotec L61, LAP, LE5 \/ GM Delta Platform\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eStock Output\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e148-173 hp \/ 150-167 lb-ft (Approx)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003ePart Number\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003eUF491 \/ 41-103\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2007 Pontiac G5 Base (2.2L I4)\u003c\/li\u003e\n  \u003cli\u003e2007 Pontiac G5 GT (2.4L I4)\u003c\/li\u003e\n  \u003cli\u003e2008 Pontiac G5 Base (2.2L I4)\u003c\/li\u003e\n  \u003cli\u003e2008 Pontiac G5 GT (2.4L I4)\u003c\/li\u003e\n  \u003cli\u003e2009 Pontiac G5 Base (2.2L I4)\u003c\/li\u003e\n  \u003cli\u003e2010 Pontiac G5 Base (2.2L I4)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Pontiac Reliability Standard\u003c\/h3\u003e\n\u003cp\u003eMaintaining precise ignition timing and robust spark delivery is critical to keeping these Ecotec-powered GM coupes running efficiently.
