NGK Standard plugs are a proven OE cornerstone that customers have relied on for decades, engineered specifically for OE applications.

• Actual OE or equivalent design: an OEM-quality nickel center electrode tip provides consistent performance.
• NGK's OE ceramic technology: high-grade alumina silicate ceramic forms a stronger insulator for optimal dielectric performance. Triple gasket sealing is designed to prevent combustion gas leakage.
• Solid copper core: a 98% pure copper core offers heat dissipation, conductivity and ultra-wide heat ranges.
• Trivalent metal plating and cold-rolled threads: the plating provides anti-corrosion and anti-seizing properties for easier installation and removal. The cold-rolled threads help prevent cross-threading and damage to cylinder heads.

Specifications: heat range 9; M14-1.25 metric thread; 19 mm (0.750 in) reach; flat seat with a crush washer included; J-gap with one nickel ground electrode, pre-gapped at 0.028 in (0.7 mm); resistor type with a non-removable terminal nut; mid-projection center electrode with a 3.0 mm (0.12 in) insulator tip projection. Country of origin: Japan.

This plug is best for vehicles that use OE nickel alloy plugs and is not recommended where factory precious metal plugs are fitted. Hard starting, misfires or fouled electrodes are signs that a plug may need replacing. The number of plugs required varies by application.
