100,000 Miles / Unlimited Months (Parts Only)ACDelco iridium spark plugs are the latest evolution in high performance plugs. The natural properties of iridium, with a melting point of approximately 700 degrees Celsius higher than platinum, help enable the plug to burn fuel more efficiently and to deliver better performance. As a result, the iridium plugs have a minimum service life of 100,000 miles (service life varies with individual driving conditions.) Since iridium is one of the densest materials found on earth, the iridium-tipped center electrode is 50 percent the size of a platinum electrode, and 20 percent the size of a conventional nickel electrode. The secondary micro-discharge of the center electrode burns off carbon deposits as they form, for superior anti-fouling performance that, along with the tapered cut-ground electrode, offers enhanced flame spread during combustion. The specially designed electrodes increase the electric field strength at the gap, reducing the voltage required for sparking to begin, for improved cold starting and quicker acceleration. The application coverage of ACDelco iridium spark plugs continues to grow, with the plugs being backed by a 100,000-mile limited warranty.
