Hello,
I am rider of MT-25. There is some information pollution about spark plug Exchange. I learned that some authorized service use iridum spark plugs instead of original ones. Can iridium spark plugs use in this motorcycle ? What are the damages and benefits ? Does it affect fuel consumption or performance ?
Best Regards
