How Often to Change Your Spark Plugs

Hands Removing Spark Plug

If you’re wondering, when to change spark plugs in your car, you’re not alone, and Sam Leman Chrysler Jeep Dodge Bloomington is here to help! Spark plugs are essential to the ignition system — you can’t start your car without working spark plugs. So, when it’s time to replace spark plugs or they go bad, it’s important not to postpone scheduling service. Read on to learn more about how often to change spark plugs, and why it’s important to do so. 

When Do I Change Spark Plugs? 

Typically, spark plug replacement is recommended after 30,000 miles or so. Spark plug replacement intervals can vary, however, depending on the spark plugs themselves. Some are higher quality and last longer than others. For this reason, it’s important to rely on our parts department for OEM CDJR parts, which are made specifically for vehicles like the Ram 1500, Dodge Journey, and others. 

What Are the Signs Spark Plug Replacement Can’t Wait? 

When a car’s spark plugs begin to fail, the signs are usually obvious. Spark plugs work by transferring the ignition’s high-voltage current to the ignition coil, which ignites the combustion chamber when you start the car. If there are problems with the spark plugs, or if they’re failing, you’ll notice the following right away: 

  • Engine is slow to start or doesn’t at all 
  • Frequent engine misfiring 
  • Rough-running engine 
  • Rough idling
  • Acceleration is slow and weak 
  • Fuel economy is lessened 

What Are the Benefits of Changing the Spark Plugs? 

Of course, the largest benefit to changing spark plugs is avoiding the problems listed above. However, there are other benefits that are worth noting, such as: 

  • Greater Fuel-Efficiency – If your car’s spark plugs are worn out, fuel economy ratings can be reduced by as much as 30%. 
  • Seamless Combustion System – When the spark plugs are operating normally, the combustion system will usually follow suit. 
  • Smooth Engine Starts – You’ll notice a difference immediately when you replace old spark plugs with new ones. 
  • Fewer Emissions – New spark plugs not only help to improve fuel economy, but also help cut down on emissions.
