My car has 50000 miles! I believe you dont need to replace them until 100 but I would like to regardless. I want to know the millimeters Im supposed to give the spark plug


Thank you

You are correct. Spark plugs do not need to be replaced till 100k miles. They are platuim plugs and really don't need to be changed, cause they do last 100k plus. But if you are looking to replace them, if you buy them from Nissan they come pre gapped. The gap is 1.1 mm ( 0.041 in)


If you have any more questions on this, please feel free to ask. Thanks Jay!
