NGK 7862 Laser Platinum Spark Plug, Semi-Surface Discharge, 5/8 Inch Hex

The NGK 7862 is a Laser Platinum spark plug built for reliable ignition performance and long service life. It uses a solid copper core for superior heat dissipation and conductivity across a broad heat range, paired with a platinum center electrode tip that resists wear far longer than a standard nickel tip. The ground electrode is finished in corrosion-resistant nickel to keep installation and removal easy over the plug's service life, and the semi-surface discharge ground configuration is designed to support consistent, reliable spark performance. With 5,000 ohms of resistance, the NGK 7862 helps suppress radio-frequency interference while maintaining strong ignition output. Its 5/8 inch hex size fits standard spark plug sockets and wrenches sized for that hex. Always check your engine's maintenance manual and use only the spark plug recommended by your engine's original equipment manufacturer -- using the wrong plug can reduce performance and fuel economy or cause engine damage. The NGK 7862 is part of NGK's Standard/Laser Platinum spark plug lineup, an OE cornerstone that has provided decades of dependable performance for engine builders and service technicians alike.
