So at this point we can say using spark plugs without the "S" at the end are safe to use?
With that being said let's just be careful and inspect them once in a while to avoid any type of corrosion, right?

Here I will issue my standard disclaimer: Beware counterfeit NGK plugs, particularly those bought on Ebay for a very good price.
Stick with a real shop or a reputable source.

Don't ask me how I know. But, NGK has a "how to spot a fake" section on their website.
