Frequently Asked Questions

Do iridium spark plugs make a difference?

Iridium spark plugs are a type of performance spark plug that is designed to provide better ignitability and durability than traditional copper spark plugs. The iridium in the plug's electrode helps to create a stronger, more sustained arc when the spark plug fires, which can result in better engine performance. In addition, iridium is much more resistant to wear and corrosion than copper, so iridium plugs typically last longer.

While there are many benefits to using iridium spark plugs, they do tend to be more expensive than traditional copper plugs. However, many drivers feel that the improved performance and longevity of these plugs is worth the extra cost. If you're looking for an upgrade from your stock copper plugs, or if you're simply wanting the best possible performance from your vehicle, then iridium spark plugs may be the right choice for you.

What is the most high quality spark plugs?

If you're looking for the most high quality spark plugs, you'll want to consider NGK or Denso. Both of these brands offer a wide variety of spark plugs that are designed to provide superior performance and long lasting durability. When it comes to choosing the right spark plug for your vehicle, it's important to consult your owner's manual or a qualified mechanic to ensure you're selecting the correct model.

What spark plugs does GM use?

GM has used several different types of spark plugs over the years. In the early days, GM used ACDelco R45TS plugs. These were replaced by ACDelco R44LTS plugs in the mid-1970s.

GM also used Champion J6C plugs in the 1970s. In the 1980s, GM began using ACDelco R43LTS plugs. These were eventually replaced by ACDelco R42LTS plugs in the late 1990s.

Today, GM uses a variety of different spark plug types depending on the model and engine type.

Do upgraded spark plugs increase horsepower?

It is a common misconception that upgrading your spark plugs will increase your engine's horsepower. This simply isn't true. Spark plugs play an important role in the combustion process of your engine, but they don't have any direct impact on horsepower.

Spark plugs create the spark that ignites the air/fuel mixture in the cylinders. This mixture is what provides power to the engine. The more efficiently this mixture burns, the more power the engine will generate.

However, it's not the spark plugs themselves that determine how well this mixture burns – it's actually the design of the combustion chamber and intake/exhaust system. There are many factors that can affect how well your engine burns its fuel mixture and increases horsepower. These include:

– Compression ratio: A higher compression ratio means there's more pressure in the cylinders, which can lead to a more complete burn of the air/fuel mixture. This results in more power being generated by the engine. – Camshaft design: The camshaft helps control when and how long valves are open during each cycle of operation.

A well-designed camshaft can help improve airflow into and out of each cylinder, which also aids in burning fuel more completely for increased power output. – Fuel quality: Using higher quality gasoline or other fuels can also lead to improved performance from your engine as they tend to burn cleaner than lower quality options.
