High Performance Ignition Coil for GMC Yukon XL 1500 2500 (2007-2014) 5.3L 6.0L 6.2L

High-Output Performance Ignition Coils for 2007-2014 GMC Yukon (Gen IV V8 / GMT900)

Direct-fit replacement ignition coil packs engineered to restore optimal spark delivery and eliminate misfires on GM Gen IV V8 engines.

The Stock Yukon Ignition Weakness

The factory Delco ignition coils on the GMT900 chassis frequently degrade after repeated heat cycles, leading to increased internal electrical resistance. Over time, the constant thermal expansion and contraction within the engine bay break down the internal epoxy potting, compromising the primary and secondary coil windings. This breakdown results in high-RPM misfires, rough idling, poor fuel economy, and flashing check engine lights under load. Hauling cargo or towing heavy trailers exacerbates heat soak, significantly accelerating OEM coil failure and reducing overall combustion efficiency.

The Engineering Solution

The UF414 high-performance replacement coils feature upgraded primary and secondary copper windings designed to exceed factory voltage output and extend spark duration. Utilizing high-dielectric epoxy and advanced internal potting techniques, these coil packs offer superior thermal management to resist severe heat soak in tight V8 engine bays. Upgraded silicone boots provide maximum insulation against voltage leaks and arching, while actively resisting degradation from oil exposure and extreme engine temperatures. By delivering a hotter, more consistent spark, these coils stabilize idle, optimize throttle response, and ensure complete combustion across the entire RPM range.
