High Performance Ignition Coil for Chevrolet Tahoe (2007-2014) 4.8L 5.3L 6.0L 6.2L

High-Voltage High Performance Ignition Coils for 2007-2014 Chevrolet Tahoe (Gen IV LS V8 / GMT900)

Upgrades the factory ignition system to deliver a stronger, more consistent spark, preventing misfires under heavy load and restoring lost combustion efficiency.

The Stock Tahoe Ignition Weakness

The OEM Generation IV LS coil packs on the GMT900 platform are prone to thermal degradation and internal resistance build-up over time. Continuous exposure to engine bay heat soak, especially during towing or long-duration high-load driving, causes the internal epoxy resin to break down. This degradation leads to weak spark outputs, resulting in partial combustion, rough idling, hesitation under acceleration, and eventual P0300-series misfire codes as the secondary winding resistance falls out of factory specification.

The Engineering Solution

These UF414 replacement upgrade coils are engineered to exceed OEM specifications by utilizing high-grade internal copper windings and a reinforced magnetic steel core. This structural overhaul significantly increases the secondary voltage output, ensuring complete atomized fuel combustion inside the cylinder even under extreme cylinder pressures. The housing is constructed from high-dielectric, heat-resistant thermoplastic that shields the internal circuitry from severe thermal cycles, effectively eliminating heat soak failures. By delivering a fatter, more intense spark, these coils promote faster flame front propagation, yielding improved throttle response, stabilized idle, and optimized fuel economy for the heavy Tahoe chassis.
