Here are some important precautions to consider when using spark plugs


1. **Correct Type**: Always use the correct type and specification of spark plug recommended by the vehicle manufacturer. Different engines require different spark plugs. 2. **Installation Torque**: Ensure that spark plugs are installed with the correct torque. Over-tightening can damage the threads, while under-tightening can lead to poor performance.

Here are some important considerations for car spark plugs

Refer to the owner's manual for specifications. 2. **Gap Measurement**: Check the spark plug gap before installation.
