Made of solid copper to current aircraft standards. Available in 14 MM and 18 MM sizes.
They were reasonably priced, shipped and received promptly, were the right size. I didnâ€™t count them, but no reason to think there were less than 100. Which should last me quite a long time - using them on a classic car with 2 plugs for each of itâ€™s 6 enormous cylinders.
Exactly as advertised!
Buy 100 of the spark plug gaskets and you will not find a better price on new gaskets.
They are round, which is good, and they fit my spark plugs, which is also good.
great value. The best price we could find.
Good price and work as expected.
was just what I needed
Heres the deal folks...All aircraft engine manufacturers specify using a NEW gaskets when removing and replacing aviation spark plugs. If you run a Repair Station or you are an A.I. you best be using NEW gaskets (and billed on your work orders) to avoid potential liability issues. These generic branded M-674 gaskets are the correct Rockwell hardness and dimensions. We use thousands of gaskets per year and these Aircraft Spruce gaskets are now our #1 choice.
Look just like OEM. More convenient than buying a box of 100.
