The ACDelco GM Original Equipment Iridium Spark Plug (41-101) represents the latest in spark plug technology, designed as an exact replacement for original equipment. Crafted with an iridium composition, these plugs provide a high melting point and superior strength, contributing to excellent wear resistance and long-term durability. The advanced material ensures optimal engine performance, delivering stable idling, reliable cold starts, responsive acceleration, and smooth overall operation. Designed, engineered, and tested to rigorous standards, these iridium spark plugs are built to meet the demands of modern engines. Key specifications include a 14mm thread size with a 1.25mm pitch, a tapered seat, and a 0.69-inch reach. The plug features a resistor for radio frequency interference suppression, with a resistance value between 4-7.5K Ohm. The hex size is 16mm, and the insulator height is 2.07 inches (52.5 mm). The gap size is pre-set at 0.06 inches (1.5 mm), although some users have noted they may require adjustment to specific vehicle requirements. This ACDelco spark plug is sold in a pack of four and is backed by General Motors. It is intended to provide a direct fit and maintain the performance characteristics of the original equipment. Compatibility information should be verified using the vehicle fitment tool before purchase.
