Setup, Compatibility & Care
Setup:
- Ensure the engine is cool before beginning.
- Carefully remove the old spark plug using the appropriate spanner size (16mm).
- Thread the new Bosch 0242229782 spark plug in by hand to avoid cross-threading.
- Tighten the spark plug to the recommended torque of 28 Nm using a torque wrench. Overtightening can damage the cylinder head, while undertightening can lead to poor performance and potential blow-by.
- Reconnect the spark plug wire or ignition coil.
Compatibility:
This spark plug is designed with specific dimensions (M 14 x 1.25 thread, 19mm thread length) and is compatible with a wide range of vehicles. Always verify compatibility with your specific vehicle's make, model, and year, or consult your owner's manual. It is known to be a replacement for OEM part numbers like Mitsubishi MD372421 and Toyota 9091901192.
Care:
Spark plugs are wear items and are not designed to be cleaned or reused once removed from service. Regular inspection during scheduled maintenance is recommended. If a spark plug appears fouled or damaged, it should be replaced.
