Spark Plugs - Function, Types, and Maintenance

Spark Plugs - Function, Types, and Maintenance | Asian Imports

Ever wonder what gives your car the kick it needs to start and keep running smoothly? The answer is one of the smallest components in your car - the spark plug. A vital part of each and every gasoline vehicle serves one purpose, which we will share below!

What Is A Spark Plug?

A spark plug is an essential component of your car's ignition system. It's a small device fitted into the cylinder head of the engine. Its primary role? To ignite the fuel-air mixture in the combustion chamber. This ignition is what powers your engine. Without spark plugs, your car simply wouldn't run. Each time your engine is operating, these plugs fire thousands of times per minute.

Types Of Spark Plugs

Copper Spark Plugs

These are the traditional, standard choices. They're known for good conductivity and are often used in older vehicles. Copper spark plugs are a bit like the classic vinyl records - not the newest technology, but they have a reliable, tested quality that works well for certain older models.

Iridium Spark Plugs

Think of iridium spark plugs as the high-performance smartphones of the spark plug world. They're more expensive, but they last longer and work more efficiently. These are particularly great for modern engines that require top-notch performance.

Platinum Spark Plugs

These are a step up from copper. Platinum spark plugs offer better longevity and a steadier spark. They're like having a reliable tablet - not as high-end as the latest gadget, but significantly more robust than the basics.

Double Platinum Spark Plugs

These are an enhanced version of platinum plugs. They're designed for even better performance and fuel efficiency. Imagine a tablet with double the battery life and features – that's what double platinum spark plugs offer for your engine.

Silver Spark Plugs

Silver spark plugs have the best thermal conductivity. They're often found in high-performance and older European cars. Think of them as a specialized tool - not for everyday use, but excellent in the right circumstances.

When To Change Spark Plugs

Now that we have explained all the different types of spark plugs, it's more than necessary to note that most of them should be changed at different intervals. Here are the requirements of each:

Copper Spark Plugs

These should be checked and possibly changed every 20,000 to 30,000 miles. It's like doing a routine check-up to keep everything running smoothly.

Iridium and Platinum Spark Plugs

These can last much longer, up to 60,000 miles, but it's always good to check your car's manual for specific recommendations. It's similar to the long-term maintenance of durable household appliances.

Double Platinum Spark Plugs

Just like the single platinum, these also typically last up to 60,000 miles. They offer the added benefit of better performance over time, much like upgrading to a better-quality appliance in your home.

Silver Spark Plugs

These generally have a lifespan similar to copper plugs. They're great for specific uses but might need more frequent checks, akin to specialized tools that require regular maintenance.
