X4XZ UF414 Ignition Coils Pack + Double Iridium Spark Plugs & 10.2mm Wires for Chevy GMC

All-in-One GM Ignition Upgrade

Upgrade your GM-powered ride with the X4XZ UF414 Ignition Coils Pack, Double Iridium Spark Plugs, and 10.2mm Spark Plug Wires. This complete kit includes eight UF414 coils, eight 41-962 iridium plugs, eight 748UU wires, and six wire buckles. It’s designed to fit a wide range of Chevy, GMC, Buick, Cadillac and related models—covering trucks, SUVs, and vans—providing a cohesive upgrade for reliable ignition performance.

Designed for real-world driving, the coil pack and plugs work together to deliver a stable, consistent spark across a broad operating range. The iridium electrodes and ceramic body are chosen for durability, while the premium silicone rubber insulation on the wires resists heat and helps prevent leakage and wear. Expect the possibility of smoother starts, steadier idle, and more confident acceleration in everyday driving or light towing scenarios. Individual results vary by vehicle, but many users notice a more predictable ignition response after a full upgrade.
