Spark Plugs

When Do I Change Spark Plugs?

This is not an uncommon question among Arcadia drivers, as most know that spark plugs are an important part of a vehicle’s engine. Generally, it’s recommended that you change spark plugs every 30,000 miles, but you’ll want to check on the specific needs of your vehicle to make sure. The service center at Mercedes-Benz of Arcadia covers how often to change spark plugs and more below!

 

 

How Often to Change Spark Plugs: Spark Plug Function 

Los Angeles drivers often ask, “When do I change spark plugs?”, but some even start with “What do spark plugs do?”. Your car has a component called an ignition coil. Spark plugs take the initial voltage this coil generates and sends them to the combustion chamber, where your engine ignites. Spark plugs help with: 

  • Combustion System: The overall health of your combustion system depends upon the quality of your spark plugs in a major way. 
  • Starting Your Engine: Spark plugs are essential for starting your engine smoothly and reliably. 
  • Fuel Economy: Worn-down spark plugs can cut your fuel economy by up to 30 percent! You also need to know how often to change spark plugs to reduce harmful emissions from your vehicle.

Spark Plugs: Symptoms to Know 

Pasadena and Alhambra drivers should schedule service for spark plug replacement according to the guidelines in their owners manual and the service menu on their vehicle, which has the most accurate answer to the question, “When do I change spark plugs?”. There are also a few obvious signs of worn down spark plugs to know: 

  • Engine makes noises while idling
  • Engine misfires 
  • Fuel Economy decreases 
  • Noticeably poor acceleration 
  • Slow and/or failed engine startup

If you notice these signs, you will want to order parts and replace your spark plugs!
