How To Change Your Car’s Spark Plugs



In most cars, the spark plugs need to be replaced after about 30,000 miles.  However, you might need to check your car manual to see if your car is any different.

Changing your spark plug might appear like serious work. Well, it is not that complex. It is a simple process that would need you to set aside some time and exercise patience. Do not rush, because you need to install the replacements in a specific order.

To change the spark plug, you would need a ratchet or a socket wrench, 12-inch socket extension and new spark plugs. Estimated time for the entire process is 20 to 30 minutes.

Well, if you are not too comfortable with doing it yourself, of course, you could contract the job to a mechanic.

Here are the simple steps to change your vehicle’s spark plug.

Locate your spark plugs in your car

Know where your spark plugs are located. Often, they are attached to thick rubbery wires.


Know The Number of Plugs

You will find either four, six, or eight plugs, depending on how many cylinders your car has.


Remove the wires connected to the plugs

Remove the wire to the first spark plug only. Do not remove all of the wires at once. Your spark plugs are installed in a certain order, which you

need to maintain.


Remove the first spark plug

Use your spark plug socket and extension on your ratchet to remove the first spark plug.


Install the new spark plug

Install the new spark plug by first screwing it in by hand, and then tightening it with a wrench for a perfect fit. Do not over screw or over-tighten it.


Re-attach the spark plug wire

Repeat these steps for each spark plug, one after the other. is an authoritative car blog in Nigeria.
