What kind of spark plugs does GM use?
General Motors (GM) vehicles typically use iridium spark plugs, which are known for their durability 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 GM Vehicles
GM has been using iridium spark plugs in many of its vehicles for several years. Iridium is a rare and expensive metal, but it provides significant benefits that make it a preferred choice for modern engines. Iridium spark plugs have a smaller electrode gap, which allows for a stronger spark and more efficient combustion. This can lead to improved fuel economy, reduced emissions, and better engine performance.
Additionally, iridium spark plugs have a much longer lifespan compared to traditional spark plugs. They can typically last up to 100,000 miles or more before needing replacement, whereas copper or platinum spark plugs may need to be changed every 30,000 to 50,000 miles.
Advantages of Iridium Spark Plugs
- Durability: Iridium spark plugs are highly resistant to wear and tear, allowing them to maintain their performance for an extended period.
- Improved Combustion: The smaller electrode gap of iridium spark plugs enables a stronger and more consistent spark, leading to better fuel combustion and engine efficiency.
- Reduced Emissions: The improved combustion efficiency of iridium spark plugs can help reduce harmful emissions from the vehicle.
- Longer Service Life: Iridium spark plugs can last up to 100,000 miles or more, reducing the frequency of spark plug replacements.
Overall, the use of iridium spark plugs in GM vehicles is a testament to the company's commitment to improving engine performance, fuel efficiency, and environmental sustainability.
