Additional Description
Understanding the "Heat" range is easy.

EXAMPLE: The heat range for a RV15YC6 is the "15" (ignore the 6, it is the gap) After you have identified the numbering system for your plug, merely raise or lower that number to change the heat range. Remember, CHAMPION PLUGS GET HOTTER THE HIGHER THE NUMBER, COLDER THE LOWER THE NUMBER.

Say you are starting with a RCJ7Y if you want a colder plug, you would use RCJ6Y if you want a hotter plug, you would use RCJ8Y
