What spark plugs does Honda use?

Honda vehicles typically use iridium spark plugs, which are known for their long lifespan and improved engine performance. Iridium spark plugs are a premium type of spark plug that offer several advantages over traditional copper or platinum spark plugs.


Iridium Spark Plugs in Honda Vehicles


Honda has been using iridium spark plugs in many of its models for several years. Iridium is an extremely hard and durable precious metal that can withstand the high temperatures and pressures inside an engine cylinder. This allows iridium spark plugs to maintain their shape and performance for a longer period compared to other types of spark plugs.


Some key benefits of the iridium spark plugs used in Honda vehicles include:



  • Longer Lifespan: Iridium spark plugs can typically last 100,000 miles or more before needing replacement, compared to 30,000-50,000 miles for standard copper spark plugs.

  • Improved Fuel Efficiency: The precise ignition provided by iridium spark plugs can improve combustion efficiency, leading to better fuel economy.li>
  • Enhanced Engine Performance: Iridium's durability allows the spark plugs to maintain a sharper electrode over time, providing a stronger and more consistent spark for improved engine power and responsiveness.


Honda recommends following the spark plug replacement intervals specified in the owner's manual for each vehicle model. Properly maintaining the spark plugs is important for optimal engine performance and fuel efficiency.
