NGK DILZKAR7C11S Laser Iridium Spark Plug – Stock 90137
This NGK Laser Iridium plug delivers a strong, consistent spark for smoother idle, clean combustion, and reliable cold starts. The fine iridium centre tip needs less voltage to fire, which helps performance and fuel economy. A platinum pad on the ground electrode improves durability and keeps the gap stable over a long service life.
