2. How to install
Allow the engine to cool and disconnect the ignition coils. Remove the old plugs, clean the plug wells and install the new plugs by hand to prevent cross-threading. Tighten them using a torque wrench according to the vehicle manufacturer’s specified torque. Reinstall the ignition coils and connectors. Professional installation is recommended.

3. Replacement indicators
Replacement may be required if the engine develops difficult starting, rough idling, hesitation, reduced acceleration, increased fuel consumption, engine vibration, misfiring or a check-engine warning. Worn electrodes, cracked insulators and excessive carbon or oil deposits also indicate replacement is necessary.

4. Advantages of genuine NGK plugs
Genuine NGK plugs provide the correct heat range, resistance, dimensions and electrode construction. They support reliable ignition, efficient combustion, consistent engine performance and longer service life. Counterfeit plugs may cause misfires, overheating, poor fuel economy and possible damage to ignition coils or the catalytic converter.
