Tools needed for spark plug replacement
Why are spark plugs so important? They ignite the air-fuel mixture in your engine’s cylinders, initiating the combustion process that powers your vehicle. Worn-out spark plugs can lead to misfires, reduced power, poor fuel economy, and even damage to your catalytic converter. Regular car maintenance, including spark plug replacement, is essential for optimal vehicle performance.

When Should You Replace Your Spark Plugs?
Knowing when to replace your spark plugs is key to preventative car maintenance. Most manufacturers recommend replacing spark plugs every 30,000 to 100,000 miles. However, this can vary depending on the type of spark plugs your vehicle uses (copper, platinum, iridium) and your driving habits. Consult your owner’s manual or a qualified mechanic for the specific recommendations for your vehicle.

“Regular spark plug checks are a must for any car owner,” says veteran mechanic Robert Johnson. “It’s a simple procedure that can save you from bigger problems down the road.”
