Chances are, if you’re a car owner, you’ve heard of spark plugs. However, many drivers aren’t entirely clear what they do. Here are some tips to help you care for your spark plugs and to know when it’s time to order new Alfa Romeo parts at Helfman Alfa Romeo of Sugar Land.

What are Spark Plugs?

In a gasoline-powered vehicle, a process known as internal combustion turns your vehicle’s fuel into a source of energy. To start, your valves fill your cylinder with air and fuel. Then the piston moves upward, compressing the mixture.

Finally, your engine ignites the mixture with a small spark, which comes from your spark plug. This action forces your piston back down and your crankshaft to turn. It creates the power needed to propel your car forward.

How Often Do I Need to Replace My Spark Plugs?

While your spark plugs are designed to withstand millions of these mini explosions, they will wear down over time.

Plus, the more you use them, the weaker your sparks become, which makes your engine less efficient and can even lead to misfiring. It’s important to check your service recommendations, both for your specific vehicle and the type of spark plugs you use.

Do I Need New Spark Plugs?

Even if you aren’t due for a replacement, your vehicle may need one, if you notice any of these warning signs:

  • Car struggles to start
  • Gas mileage is consistently low
  • Engine rattles or knocks when idling
  • Check engine light is on
