- Plug type
- Standard glow plugs and turbo (conical seat) plugs are not interchangeable; match what your engine head uses The wrong type will not seal and can damage the head.
- Heat range
- Use colder plugs for higher nitro content, hot weather or high-compression engines; hotter plugs for lower nitro or cold conditions The wrong heat range causes poor idle, pre-ignition or quick plug failure.
- Idle bar
- Plugs with an idle bar protect the element from raw fuel in some engines They can improve reliability where fuel splashes the element.
- Spark plugs for gas engines
- Use the spark plug type specified by your gas engine maker Thread, reach and heat range must match the engine.
