Changing the plugs in a stock 13B... I have a new set of NGK plugs (part no BR9ES) and wanted to check if they are a good replacement. Or, is there other models that will provide better performance? thx...
I have stock coils, but that's my next upgrade. So, I think you are saying: good plugs, and I can use them when I add the headers and new coil..... is that right?
