IMPORTANT
The R6725-11 is a competition spark plug, not a standard replacement plug.
A colder heat range is not automatically better. Plug selection should be based on engine specification, power level, boost, fuel and intended use.
For primarily street-driven engines, an excessively cold competition plug can be more prone to fouling during low-load operation.
Contact RSG if you are unsure which competition plug is appropriate for your engine.
