How do Champion iridium plugs change ignition and longevity?

Iridium-tipped electrodes are much harder and wear-resistant than standard materials, giving a finer center electrode for a more focused, reliable spark. That precision tends to maintain efficient combustion longer, so the plugs typically provide stable starting and steady throttle response over extended intervals.

• Iridium center electrode for long-term durability
• Smaller electrode tip produces a concentrated spark
• Reduced electrode erosion compared with conventional plugs
• Engineered to meet industry and OE standards for fit and life

What exact gap and specifications should I expect from these plugs?

The Champion set ships pre-gapped close to the factory specification for the 3.6L V6, typically about 0.043 inches (often rounded or noted as 0.044 in some listings). Always check and, if necessary, adjust the gap to your vehicle’s service manual before installation to ensure optimal ignition timing and performance.

• Typical gap: approximately 0.043 in (listed also as 0.044 in some references)
