Everyone should keep a set on hand. But why would you buy the box of 100? Heck, they dont go bad and you will use all of them eventually.

Q: Are these spark plug gaskets sold in smaller quantities than 100?
We also sell generic 18mm spark plug gasket individually. See part # 07-00877 to order small quantities.
