  • Installation guide

    In need of a new spark plug? A fresh ACDelco plug will do the trick. Here's a quick and easy guide on how to install it.

    • To start, pop the hood of your car and locate the wire that connects to the spark plug. Once you've found it, gently remove the boot by twisting it counterclockwise.
    • Next, take out the old spark plug by unscrewing it with a ratchet or socket wrench. You may need a spark plug socket to do this - if so, just screw it onto the end of your ratchet or wrench.
    • Once the old plug is out, inspect it for damage before discarding it.
    • Now it's time to install the new ACDelco spark plug. Screw it in by hand until you feel resistance, then finish tightening with your ratchet or wrench. Don't over-tighten, which could damage the threads.
    • Finally, reattach the spark plug boot by twisting it clockwise, and you're all set! Following these steps, you'll have a new ACDelco spark plug installed in no time and your engine will be running smoothly.

    Thanks for choosing ACDelco!
