Hello,

The spark plug replacement procedure is fairly straight forward.
It can be done in relatively short period of time depending on your comfort level.

Before you remove the plugs you will have to take the wires off of the plug. Be sure to keep track of which wire goes to which plug. Sometimes it is just easier to do one at a time, that will make it easy to track the location of the wires.

The gap for the plugs should be at: 1.08 - 1.18 mm (0.042 - 0.046 in)


Here is a helpful guide for replacing spark plugs:

I have attached the replacement procedure for your reference.

Please let me know of any questions.
Thank you.
