Technical spark plug gap

Its always good practice to check pregapped plugs. They might leave the factory with the correct gap but you dont know what has happened to them or how they have been handled in the interim. Someone could have unwrapped it for whatever reason, then accidently dropped it and closed the gap up slightly then put it back in the packaging.

I can't find my sparkplugs. I think the dealer stole them when it went in for service.
 
I have to agree with the others, ALWAYS check the gaps on your plugs before putting them in.
