Each plug has a platinum center-wire firing tip for improved performance and durability, a yttrium-enhanced ground electrode for heat transfer, and a full platinum tip designed to limit gap erosion. Compared with standard plugs, the necked-down center electrode is described as firing faster and cleaner with less voltage, aiding starts, acceleration and fuel efficiency.

A high-nickel-alloy side electrode helps maintain the gap, and each plug has a heat-fused, leak-proof resistor. The plugs carry a 4 year limited manufacturer warranty. Autolite makes spark plugs for foreign and domestic vehicles, including iridium, platinum, double-platinum and small-engine types.

The company began making buggy lamps in 1911 and later moved into spark plugs; by 2007, it had made over 10 billion plugs. It continues to develop designs for modern engine and emissions requirements.
