High Performance Ignition Coil for GMC Savana 1500 2500 3500 4500 (2008-2019) 4.8L 5.3L 6.0L

High-Output UF414 Ignition Coils for 2008-2019 GMC Savana (Vortec V8 / GMT610)

Replaces degrading OEM ignition coils to eliminate misfires, restore lost fuel economy, and deliver a consistently strong spark under heavy load conditions.

The Stock GMT610 Ignition Shortcomings

The factory GM coil packs on the Gen IV LS-based Vortec engines are notoriously susceptible to thermal degradation over extended mileage, particularly within the cramped, poorly ventilated engine bay of the GMT610 van chassis. As the internal epoxy and secondary windings endure thousands of extreme heat cycles, internal resistance naturally increases. This physical breakdown leads to weak spark delivery, intermittent cylinder misfires (frequently triggering P0300-series OBD-II codes), sluggish throttle response, and a noticeable drop in towing capability. Heat soak is the primary failure point, degrading the coil's internal insulation and causing spark blowout under heavy engine load.

The Engineering Solution

These upgraded UF414 replacement coils resolve OEM failure points by utilizing higher-grade internal copper windings and high-temperature epoxy resin potting. This advanced construction significantly lowers primary resistance while maximizing secondary voltage output to the spark plugs. The improved thermal management prevents the heat soak-induced voltage drops common in heavy-duty commercial van applications. By delivering a hotter, more stable spark with increased duration, these coils guarantee complete combustion within the cylinder. The result is a smoothed-out idle, optimized low-end torque for moving heavy payloads, and highly reliable ignition timing across the entire operating RPM range.
