Installation Notes and Tips

Verify the engine calls for NGK DR8EA / 7162 specifications before installation. Check the plug gap against the vehicle service information, since listed fitments reference 0.024 in. to 0.025 in. gaps in some applications while the plug is pre-gapped at .028 in. Inspect the ignition wires, coil output, and cylinder head threads during service, and torque the plug to the manufacturer’s specification for the vehicle.
