Spark Plugs

[the Ferret]

Ok my plugs came in today from the ebay seller (can't complain about the service lol) and I was able to compare them to the set I already had in stock. Identical..EXCEPT... the crush gasket as stated by NGK. The" S" on the specified plug from Honda does indeed mean special gasket

If you look closely at the plug on the right in the pic you can clearly see the difference in gaskets. The "S" gasket is both smaller in diameter and thinner than the one on the plug with the same designation without the "S" on the left.

Now here's the thing.. I can't for the life of me figure out why that would make a difference? It must for some reason, but I have no idea why? Maybe takes less torque to crush the smaller ones? Maybe someone who has taken their old plugs out can explain it? or some engineer type?

I'm thinking about calling the ebay seller, Sixity Auto, to see what they have to say. They may have to go back.
