Mounted directly to the valve covers, these factory units are subjected to extreme heat soak from the exhaust manifolds and cylinder heads. Over time, the internal epoxy and secondary windings break down, resulting in weak spark output. This degradation manifests as rough idling, hesitation under acceleration, increased fuel consumption, and inevitable P0300-series misfire codes, especially when towing or operating under high-load conditions where elevated combustion pressures demand maximum spark energy.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis 8-pack of UF414 ignition coils is engineered to exceed OEM specifications and deliver a significantly stronger, more consistent spark. By upgrading the primary and secondary winding materials with high-grade copper wire, these coils offer lower resistance and higher voltage output. The housings are constructed from heat-resistant dielectric polymers to combat heat soak, while the improved internal epoxy potting resists vibration and prevents internal shorting. The result is a more complete combustion event inside the Gen IV Small Block, translating to restored horsepower, smoother idle characteristics, and reliable ignition timing even during heavy towing applications. Designed for a direct plug-and-play installation, they require no modifications to the factory wiring harness or ECM.\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;\"\u003e2007-2013 Chevrolet Avalanche\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;\"\u003eGen IV V8 (5.3L, 6.0L) \/ GMT900\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;\"\u003e310-366 hp \/ 335-376 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;\"\u003eUF414\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2007-2013 Chevrolet Avalanche 5.3L V8 Models\u003c\/li\u003e\n  \u003cli\u003e2007-2013 Chevrolet Avalanche 6.0L V8 Models\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Chevrolet Towing Caliber\u003c\/h3\u003e\n\u003cp\u003eFor a heavy-duty platform like the GMT900 Avalanche, dependable torque delivery is non-negotiable.
