NGK Standard spark plugs are OE-approved and recommended for reliable performance for most automotive and non-automotive applications. NGK Standard spark plugs feature a 5-Rib insulator design to prevent flashover and are also treated with corrosion-resistant plating to ensure ease of installation and removal. Cold-rolled threads prevent damage to cylinder head. NGK’s triple gasket sealing process virtually eliminates gas leakage past the shell. Solid Copper Core provides superior heat dissipation, conductivity and a broader heat range. FEATURES Cold-rolled threads – prevent damage to the cylinder head Triple gasket sealing process – virtually eliminates gas leakage past the shell Solid Copper Core – provides superior heat dissipation, conductivity, and a broader heat range Trivalent Plating – a three three-step plating process utilizing silver chromate and zinc ensures maximum corrosion resistance SPECS CR9E CR10E CR9EK CR10EK Center Electrode Core Material: Copper Core Copper Core Copper Core Copper Core Center Electrode Tip Material: Nickel Nickel Nickel Nickel Electrode Core Material: nickel nickel nickel nickel Electrode Tip Material: nickel nickel nickel nickel Gap Size: 0.032 in 0.032 in 0.028 in 0.028 in Ground Configuration: Standard Standard Standard Standard Ground Electrode Core Material: Nickel Core Nickel Core Nickel Core Nickel Core Ground Electrode Quantity: 1 1 2 2 Ground Electrode Tip Design: Standard Standard Standard Standard Ground Strap Quantity: 1 1 2 2 Hex Size: 5/8 5/8 5/8 5/8 Manufacturer Heat Range: 9 10 9 10 Reach: 19 mm 19 mm 19 mm 19 mm Resistor: Yes Yes Yes Yes Seat Type: Gasket Gasket Gasket Gasket Shorty Spark Plug: No No No No Thread Diameter: 10 mm 10 mm 10 mm 10 mm Tip Configuration: Stud Stud Stud Stud Type: Standard Standard Standard Standard Wrench Diameter: 5/8 in 5/8 in 5/8 in 5/8 in
