If you read those articles they will explain exactly what spark plug heat ranges mean. Its complex and hard to explain with just words, pictures help.
Bottom line, unless you are running 300rwhp you need stock heat range plugs. If you run colder ones, you will foul them out. NGK iridiums can be found here for $39+ shipping. |
