How to Choose FT7C Spark Plug

Choosing the right ignition plug for a vehicle can be a daunting task. But it doesn't have to be. Here are some tips for choosing the right FT7C spark plug:

  • Consider the vehicle's requirements

    Every vehicle comes with a user's manual that states the recommended spark plug to use. This is because the manufacturer takes into consideration the engine type, fuel type, and other important factors. The user's manual should be checked first before making a choice.

  • Check the heat range

    The heat range is an important factor to consider when choosing a spark plug. The heat range determines how fast the heat is conducted from the center electrode to the body of the plug. A plug with a higher heat range will run hotter and vice versa. Spark plugs with a low heat range are used in FT7C engines because the engine generates less heat compared to others.

  • Evaluate the material

    The material used to construct the spark plug is also an important factor to consider. Spark plugs are made with different materials, and each one has its advantages and disadvantages. For example, a plug made with copper offers great conductivity and durability, but it is not as popular as the FT7C plug, which is made with iridium.

  • Match the electrode design

    The electrodes of the spark plug are responsible for generating sparks that light up the air-fuel mixture in the combustion chamber. Iridium and platinum are some materials used in making the electrodes. They are great choices for modern engines and provide a reliable spark.

  • Consider driving conditions

    For someone who drives mostly within the city, a spark plug with a standard gap is the right choice. But for those who drive on highways or engage in extreme conditions, a spark plug with a wider gap is recommended.

  • Brand reputation

    When choosing an FT7C spark plug, the brand to choose should be well-known. There are many manufacturers of spark plugs, but not all of them produce quality plugs. It is important to look for a reputable brand that offers quality products.
