Good Morning,I am sure it has been asked before,but could someone in the cub tell Me the overall best Spark plugs to fit My Mini.I am looking for happy medium Fuel economy/Performance.This Mini does not have the Turbo.Plus any tips on changing these plugs Myself.Thank you happy Owner...Kenneth

 

I installed the factory oem plugs, that is what the maker spec'd. The manual says 100,000 mile change intervals, but I changed them out at 55,000.

 

So by Clubman STD you mean non S right? Not the D as in diesel that the rest of the world gets?

How many miles do you have now?
