Properly dispose of the old spark plugs according to local regulations.

It is recommended to consult your vehicle's owner's manual for specific instructions on replacing spark plugs for your particular make and model. If you are unsure or uncomfortable performing this task, it is best to seek the help of a professional mechanic.
