NGK Iridium Spark Plug

The NGK 95112 is a Laser Iridium spark plug engineered specifically for the performance enthusiast. Its design centers around a fine wire iridium alloy center electrode, which boasts an extremely high melting point and ensures high durability, delivering a consistently stable spark vital for today's high-tech, high-performance engines. This construction is further enhanced by trivalent metal plating, offering superior anti-corrosion and anti-seizing properties, while corrugated ribs are integrated to prevent flashover. The plug's pure alumina silicate ceramic insulator provides exceptional strength and superior heat transfer capabilities, complemented by a copper core that aids in heat removal. Triple seals are incorporated to prevent leakage, ensuring reliable performance. Key specifications include a 12mm thread diameter with a 1.25mm pitch, a gasket seat type, a 26.5mm reach, and a 9/16" hex size. The terminal type is solid, and the gap is set at .031". NGK's Laser Iridium spark plugs are built for longevity, with an estimated lifespan of 100,000 miles under typical OEM application conditions. Installation requires specific torque settings: 10.8-18 lb. ft. for cast iron cylinder heads and 10.8-14.5 lb. ft. for aluminum heads. The recommended heat range is 8, and it features an extended metal shell design. The plug has a resistor value of 5k Ohm. This NGK 95112 spark plug is designed for a variety of Honda Civic models from 2016 to 2021, including EX, EX-L, LX, Sport, Sport Touring, Touring, and Type R trims.
