Hello, I have an Aerox with a PM Tuning 70 kit.. I'm currently using NGK's BR9ES as my spark plug. I was wondering if anyone could think of a better one that would improve performance? As I would like an iridium one, but I'm not sure which will fit. Thanks, Alex
A spark plug isn't a performance part. It does one job. Make a spark. Use the correct one for your bike and that's it. Simple enough.
