Ignition Coil & Iridium Spark Plugs for Chevrolet Uplander (2006-2008) 3.9L V6

Direct-Replacement Ignition Coil & Iridium Spark Plugs for 2006-2008 Chevrolet Uplander

Designed to restore optimal combustion efficiency: This comprehensive ignition kit replaces degrading factory coils and plugs to eliminate misfires, rough idling, and voltage leaks in your 3.9L V6 engine.

The Stock Uplander Ignition Shortcomings

The OEM ignition system on the 3.9L High Value V6 is notoriously susceptible to thermal degradation and primary winding failure. Situated in the compact U-Body engine bay, the original coil pack is subjected to intense, prolonged heat soak. Over thousands of heat cycles, the factory epoxy resin begins to crack, leading to internal arcing, high RPM misfires, and a noticeable drop in throttle response. Furthermore, standard factory plugs can foul prematurely, increasing electrical resistance and forcing the ignition coil to work harder, which ultimately accelerates catastrophic failure across the entire ignition circuit.

The Engineering Solution

This upgraded ignition coil and spark plug package is engineered to deliver sustained, high-voltage spark energy under extreme thermal loads. The replacement coil pack utilizes high-grade copper windings and a reinforced, high-dielectric epoxy housing to prevent electrical tracking and resist heat-induced cracking. Paired with ultra-fine wire iridium spark plugs, the system requires less firing voltage while providing a concentrated, hotter spark for complete fuel atomization. Additionally, the included heavy-duty silicone spark plug wires feature EMI/RFI suppression shielding and thick insulation to protect against parasitic voltage drops. The result is a smoother idle, restored factory fuel economy, and consistent power delivery throughout the entire rev range.
