1 Temp Range Colder Plugs?

Does anyone know if they make any spark plugs 1 temp range colder for the 2.0litre engines?

There should be some available. I don't know how other companies label their plugs but an example for Bosch would be a FR7DCX plug. The number 7 indicates the heat range. You want a colder plug, just go buy the FR6DCX instead. Wherever you buy sparkplugs from should have the breakdown of the part number in the catalog. Here is some more good reading.
