ACDelco Professional Iridium Spark Plugs Are The Latest In High-Performance Technology

GRAND BLANC, MICH. - ACDelco, a leader in the automotive aftermarket, continues to offer its customers new, technologically-improved products, as evidenced by the ACDelco Professional Iridium spark plug.

Throughout its 76 years of selling spark plugs, ACDelco has developed a broad range of plugs designed to perform in all types of automotive applications. The ACDelco Professional Iridium plug launches the next generation of high-performance spark plugs.

"Iridium is one of the strongest, densest precious metals on earth," said Michelle Glazier, ACDelco product specialist for spark plugs. "And with a 100,000-mile limited warranty offered by ACDelco, customers can be confident that these spark plugs are built to last."

With a melting point approximately 700 degrees Celsius higher than platinum, ACDelco Professional Iridium spark plugs are able to burn fuel more efficiently and deliver better performance. The ACDelco Professional Iridium spark plug also requires less precious metal for the electrodes than platinum-tipped plugs, while still outperforming them.

"If you look at an iridium tip, it's equivalent to about the size of two pinheads," Glazier said. "It's less drain on the electrical system because it's smaller, and it's a more efficient use of the energy in your vehicle."

Specially designed electrodes on the ACDelco Professional Iridium spark plug increase electric field strength and reduce sparking voltage, resulting in improved cold starting and quick acceleration.

A tapered, cut-ground electrode offers enhanced flame spread during combustion, while a secondary microdischarge of the center electrode burns off carbon deposits, providing superior antifouling performance.

Currently, ACDelco Professional Iridium spark plugs are available for certain 2002/2003 Chevrolet, Buick and Pontiac vehicles. Since these vehicles come equipped with iridium plugs, they must be used as the replacement. However, there are some applications where the iridium may be used as an upgrade to the current system.

The ACDelco Professional Iridium spark plug is the newest in ACDelco's spark plug line, which also includes Professional Platinum spark plugs, RAPIDFIREŽ Platinum spark plugs, conventional spark plugs, nonautomotive spark plugs and Glow plugs. ACDelco's "All Makes/All Models" family of spark plugs covers GM, Ford, Chrysler, Toyota, Nissan, Honda and virtually every vehicle on the road today.

ACDelco is a global leader in automotive replacement parts and services offering products for virtually all vehicles. ACDelco is headquartered in Grand Blanc, Mich., and markets automotive replacement parts worldwide under its brand name. For more information, visit the ACDelco Web site at acdelco.com.
