Description

The ACDelco Iridium Spark Plug 41-156 is an original equipment iridium spark plug designed to provide excellent wear resistance and durability. It features an iridium composition for a high melting point and great strength. This spark plug offers reliable cold starting, smooth performance, and quick acceleration.

Its three-piece fired-in suppressor seal meters spark energy for long electrode life, prevents combustion leakage, and helps block radio frequencies that can affect vehicle electronics. The laser-welded construction ensures precision welds and increased durability.
