The 1612 T4RAI-15 is an iridium spark plug with a 0.059-inch gap, designed for high-compression engines. It is suitable for older Buick GL8, Chevrolet, and other American vehicles. Its core advantage lies in its iridium electrode design. The iridium electrode and tapered seat design improve combustion efficiency while significantly reducing ignition voltage requirements, enhancing low-temperature starting performance, and extending service life to 40,000 kilometers.
