"7" series spark plugs
have a colder heat range than "6" series and are, therefore, commonly
used as an alternative plug on cars consistently run at high speeds or
heavy loads. Running too cold of plug for short trips will lead to fouling. This is more of a problem in the winter.
"P" in the NGK plug designation signifies Platinum electrodes. These are more expensive but last a bit longer. It is ok to run copper "C" plugs in the application that originaly had platinums as a cost savings but they will requre more frequent sevice.
