Just came back from Kragen's Auto Parts for sparkplugs and have a question.
 

I found these NGK spark plugs, silver in color, and only $2 each! What kind were those? I told the employee to look up on the computer for Platinum ones, and found them to be $12 each. Now, anyone know what kind were the $2 ones? Which one would you prefer? I saw Bosch ones too, but was kinda skeptical. Thanks.

Those are the coppers. NGK coppers to be exact. They're good for Maximas.
