Ignition Coil & Spark Plug for GMC Yukon Yukon XL 1500 2500 (2007-2016) V8 (Round Style)

High-Energy Ignition Coil & Spark Plug Kit for 2007-2016 GMC Yukon

Direct Replacement Ignition Upgrade: This complete round-style coil, spark plug, and wire kit replaces degraded factory ignition components to eliminate misfires and deliver 20% more spark energy for your V8 engine.

The Stock Yukon Ignition Weakness

The factory ignition coils on the 2007-2016 GMC Yukon are highly susceptible to heat soak and vibration degradation. Over thousands of intense thermal cycles, the internal epoxy potting breaks down, allowing moisture intrusion and leading to primary and secondary winding short circuits. This mechanical fatigue results in weak spark delivery, persistent cylinder misfires under load, rough idling, and diminished towing performance. Furthermore, aging factory plug wires increase electrical resistance, compounding the weak discharge energy reaching the combustion chamber and triggering diagnostic trouble codes.

The Engineering Solution

This comprehensive ignition overhaul kit addresses OEM shortcomings by utilizing superior internal construction. The upgraded UF414/D514A round-style coils feature premium durable copper wire windings encased in a high-dielectric epoxy resin, yielding a 61:1 turns ratio and a maximum voltage output of 32,000V. This translates to a 20% increase in discharge energy over factory coils, ensuring a stronger, more consistent spark across the entire RPM range. Paired with matched spark plugs and low-resistance 748UU wires, this system optimizes fuel atomization and combustion efficiency. The direct plug-and-play blade terminals and exact OEM fitment restore lost horsepower, stabilize idle, and maximize pulling capability without requiring ECU modifications.
