How are these iridium plugs and wires built to perform?

The plugs use a fine iridium center electrode and come pre‑gapped to 0.04" (1 mm) for consistent spark delivery. The wires are matched to the plugs and engineered to maintain insulation and low resistance across operating temperatures.

• Fine iridium electrode for stable spark and longer electrode life
