Top 4 Best Spark Plugs for BMW 2017 Market

What is the Major Function of Spark Plugs in Cars?

A spark plug is used in internal combustible engines. It is an electrical device. It is installed in the cylinder head of the engine (internal combustible engine). Gasoline is sprayed as an aerosol in the cylinder and is compressed.

Once compressed, the spark plug starts generating sparks to ignite the compressed gasoline which is in the form of an aerosol. Internal combustion engines can be divided into two categories such as:

  • Spark-ignition: Spark plug is used in spark ignition internal combustible engines. In these engines, fuel is ignited by the spark generated by the spark plug.
  • Compression-ignition: Glow plugs, which are excellent of cold weather, are used in such engines. The air is compressed in a chamber, where the fuel is injected. Compressed air mixture is heated; therefore, the fuel is ignited as soon as it is injected into the chamber.

What are the Different Types of Spark Plugs Available for BMW Cars?

There are many types of spark plugs available. However, you should have some knowledge about each of them so that you may get the best spark plugs for BMW car that you own. Spark plugs can also be categorized based on the type of grove side electrode they have. The different types of grove side electrode are “U,” “V” and “Split.”

The various types of spark plugs are:

  • The copper spark plug has a core of solid copper. However, the central electrode (2.5 mm diameter) has nickel alloy at its ends. This spark plug has the largest diameter of the electrode. The voltage required to initiate the spark indirectly proportional to the diameter of the electrode. Also, Nickel alloy is softer as compared to Iridium or Platinum.
  • The Single Platinum Spark plug is mostly similar to the Copper spark plug in design. The difference is that it has a platinum disc welded at the top of the central electrode.
  • Double Platinum spark plugs are designed to overcome the problem of waste sparks. The problem of waste Sparks was seen in single platinum and copper spark plugs. To overcome this problem, an additional platinum disc is welded on the tip of side electrode as well. This results in getting sharp edges on both the electrodes.
  • Iridium Spark plugs are most effective spark plugs. They have an Iridium tip on the central electrode and Platinum tip on side electrode. The Iridium tip reduces the diameter of the central electrode to 0.4 mm. So it uses less voltage and also resolves the problem of waste sparks.
