Spark Plug Replacement DIY (the ULTIMATE Guide)

If your spark plugs need to be replaced, it’s not a difficult job to do yourself. You’ll need a few tools and supplies, but it’s a relatively easy task that most people can complete in about an hour. The first thing you’ll need to do is locate the spark plugs on your vehicle.

Finally, use your ratchet or wrench to tighten them just enough so that they’re secure. And that’s all there is to it! Replacing spark plugs isn’t difficult, but it’s important to make sure that you do it carefully so that you don’t damage any of the parts involved.
