If you face frequent issues with the engine of your car or your car runs rough, there is something wrong with the spark plug. That means you need the best spark plug for your vehicle. Spark plugs play a crucial role in the automotive industry since the day they are invented. They are simple pair of electrodes that ignite the spark at high voltage. These are simply a vital part to operate the engine properly.
Now the question arises that why spark plugs are that important. This inexpensive product plays an important role in the combustion of your engine and has a great impact on its overall performance.
Currently, four types of spark plugs rule the industry:
- Copper Core: These are cheap and being good conductors delivers best performance. Capable of covering 20, 000- 40, 000 miles.
- Iridium: Less conductive material but operates at much lower temperature. Goes for 40,000- 60, 000 miles.
- Platinum: Prone to overheating but lasts 2x longer than copper spark plugs.
- Double Platinum: Improved version of Platinum ones. Much longer life span and much better performance.
