Understanding Spark Plugs and When to Replace Them

What Exactly Do They Do

If you have ever been in a car, chances are you have heard of spark plugs. But what exactly do spark plugs do? And how often should they be replaced? In this blog post, we will discuss the basics of spark plugs and when it is time for them to be replaced.

What is a Spark Plug?

A spark plug is an important component of your car’s engine. Its function is to ignite the air-fuel mixture inside the cylinder of your engine so that it can combust properly and generate power. A spark plug consists of two parts: the body and the tip. The body has a threaded portion that screws into the cylinder head, while the tip passes an electrical current from the ignition coil to create a spark that ignites the fuel-air mixture. Without this spark, your car won’t run efficiently or at all!

When Should I Replace My Spark Plugs? As with any part in your car, spark plugs need to be replaced periodically in order for your car to continue running smoothly. Generally, most cars will require new spark plugs every 30,000 miles or so. However, if you drive in extreme conditions such as high altitudes or extreme temperatures, then your spark plugs may need to be replaced sooner than usual (15,000 miles). It is also recommended that you check your vehicle’s owner's manual for specific instructions on when to replace them as there may be slight variations depending on make and model.

Spark plugs are essential components of any vehicle’s engine; they ignite the fuel-air mixture inside each cylinder so that it can combust properly and generate power. While most cars require new spark plugs every 30,000 miles or so—depending on driving conditions—it is always best practice to check with your vehicle’s owner's manual for specific instructions on when to replace them as there may be slight variations depending on make and model. Taking these steps will ensure that your vehicle runs efficiently and safely for years to come!
