How to use

Ensure the engine is cool and the ignition system is switched off before starting. Remove the ignition coil or spark plug lead, then extract the old spark plug with a suitable socket. Inspect the cylinder and plug well for oil or debris before fitting the new spark plug. Apply the correct torque and set the spark plug gap according to the vehicle manufacturer's specifications. Reinstall the ignition coil or lead, and verify engine operation and idle quality after installation.

Recommendations

Follow vehicle manufacturer service intervals and use specified torque and gap settings. Use anti-seize or dielectric compounds only if recommended by the vehicle maker. If persistent ignition faults remain after replacement, inspect coils, leads, fuel and air systems, and engine management diagnostics.
