Product Description
How often should spark plugs be replaced?
A common question for many vehicle owners is "When should I change my spark plugs?"
Well, not all spark plugs are rated for 100,000 miles. In fact, some car makers recommend replacement at 30,000-mile intervals.
So always follow the spark plug service intervals shown in your owner’s manual to figure out when to replace spark plugs.
If you can’t remember when you last changed your spark plugs, you can pull them and check the gap and their condition.
Spark plug after consumption
Spark plugs are daily consumables and need to be replaced regularly.
- Changing spark plugs takes about an hour (for a four-cylinder engine) and will save you at least a hundred bucks in labor.
Project step-by-step
Step 1: Remove extras and clean your work area: Blow away the crud
Step 2: Remove the ignition coil and/or boot
Step 3: Unscrew the plug
Step 4: Gap the plugs
Step 5: Install the new plug: Use the proper amount of torque
Step 6: Lube the spark plug boot and button it up
- Change your spark plugs yourself to maintain peak performance and high gas mileage. In most cases it's a simple job as long as you have the right tools.
