How Often to Change Spark Plugs

Spark plugs are vital to the operation of an internal combustion engine. Without spark plugs, your vehicle won’t go anywhere because they ignite the gas-air mixture to power your pistons moving up and down.

Ever wonder how often to change the spark plugs in your vehicle? Experts generally recommend replacing spark plugs every 30,000 miles. However, it can vary depending on your specific model. Check your owner’s manual for exact details.

Find out more information about how often to change spark plugs with our handy guide. Then, contact our Allen Samuels CDJR Aransas Pass service center if you need help with your spark plugs. We’re happy to help you in any way we can!

When Do You Change Spark Plugs?

Your Jeep spark plugs work by moving the high-voltage current from the ignition coil connected to one end of the component to ignite the combustion chamber as soon as you start your vehicle. Fuel injectors atomize gasoline in the chamber, and then air gets added. The spark plugs ignite the gas, and it pushes the pistons downward in the right order to send power to the transmission and hence the wheels.

If the spark plugs aren’t functioning properly, you’ll see problems in the performance of your vehicle. You might see issues like:

• Slow or no start
• Engine misfire
• Engine is running rough
• Rough idling
• Poor acceleration
• High fuel consumption
• Worse fuel efficiency
