Chevy Spark Plugs

While almost everyone can tell at least one of the functions fulfilled by spark plugs, just a few know about their role in heat transfer. Besides providing a spark that ignites fuel, the plugs contribute to reducing combustion temperature in the cylinders. In the meantime, the plugs themselves may get too hot or remain colder than needed. Overheating plugs can lead to pre-ignition and engine knocking, while cold plugs are not able to effectively burn carbon deposits on their surface. Hence, choosing the most suitable set of spark plugs for your vehicle is important; fortunately, there’s no shortage of choices.

All of these parts have a center electrode surrounded by a ceramic insulator and the side one that is grounded. The plugs are screwed into the cylinder head, with the electrodes protruding into the cylinders. The most spread center electrodes are made of copper and nickel, while many high-performance models have a thin iridium or platinum center electrode. Its small diameter increases the spark's energy, while the precious metal provides higher resistance to burning out and melting.
