How do you replace a Hyundai spark plug?

Answer by  jeffw (173)

Obtain the correct replacement plugs from your local auto parts store. Take care when removing the spark plug wire that you twist and pull on the boot not on the wire itself. Only change one plug at a time so that you don't mix up the spark plug wires. Gap the plugs with a feeler gauge before installation.

You are going to need to contact the Hyundai dealer themselves. Buying a Hyundai spark plug outside the dealer is called "aftermarket" parts, and usually, these do not fit properly. At the bare minimum you will have to purchase one from the dealer themselves. Whether or not you decide to pay them to install it is your choice.

Make sure you have the proper socket, extension, and socket wrench first. Insert socket over the old plug. Remove turning counter clockwise. If it sticks give the wrench a sharp jerk to loosen the plug. The old plug gets put in turning clockwise. Tighten to reccomended torque for your vehicle.
