High Performance Ignition Coil for Chevrolet Suburban 1500 2500 (2007-2014) 5.3L 6.0L

Upgraded High-Output Ignition Coils for 2007-2014 Chevrolet Suburban (Gen IV V8 / GMT900)

What it Does: Replaces the weak factory ignition system to eliminate misfires under heavy load, ensuring stable spark delivery and optimal combustion for Gen IV V8 engines.

The Stock GMT900 Ignition Weakness

The OEM ignition coils on the 2007-2014 Suburban (especially the 5.3L and 6.0L Vortec variants) are prone to thermal degradation due to their placement near the exhaust manifolds. Constant heat cycling causes the internal epoxy to crack, breaking down the primary and secondary winding insulation. This leads to voltage leakage, high-RPM misfires, erratic idling, and reduced towing capacity. Over time, increased resistance within the factory coil packs diminishes spark energy, forcing the engine control module to compensate, which subsequently harms fuel economy and increases emissions.

The Engineering Solution

These UF414 replacement upgrade coils exceed standard OEM specifications by utilizing advanced thermal-resistant housing materials and high-grade copper internal windings. By optimizing the winding ratio and employing superior magnetic steel cores, these coils increase maximum voltage output and spark duration. This ensures a complete burn during the combustion cycle, effectively resolving hesitation and stumbling under heavy throttle. The upgraded dielectric epoxy resists heat soak from the GMT900 engine bay, preventing premature failure. Direct plug-and-play fitment ensures seamless integration with the factory wiring harness, restoring lost power, improving throttle response, and providing reliable ignition performance when towing or hauling heavy payloads.
