Key specifications
Thread diameter: 12.7 mm
Function: spark plug for petrol engine ignition
Application: single-cylinder and multi-cylinder petrol engines where 12.7 mm plugs are required
Installation: threaded fitment into engine cylinder head
Operation: provides electrical discharge point for fuel-air mixture ignition
How to use
Ensure the engine is cool and the ignition system is de-energized before starting installation. Remove the ignition lead or coil from the old spark plug, unscrew the used plug with an appropriate socket, and inspect the cylinder head for debris. Thread the new spark plug by hand to avoid cross-threading, then tighten to the manufacturer's recommended torque specification using a torque wrench or the correct socket with a torque extension. Reconnect the ignition lead or coil and verify secure electrical connection before starting the engine.
Usage recommendations
Refer to the vehicle manufacturer's service manual for the correct spark plug gap, torque values, and replacement intervals. Use the 12.7 mm spark plug only in engines specified to accept that thread diameter and follow standard safety precautions when working on the ignition system, including wearing eye protection and ensuring the ignition is switched off.
