NGK NGK NGK NGK,,,,, is there any other brand of non-iridium plug? come to think of it i've been riding for three years and have never once heard of anyone talking about a brand other then ngk so kudos for the Denso, now i am aware of two brands. Does anyone know a good source of information about the performance differences of spark plug brands in say one specific size. What company makes plugs for the Like 200i? And what one is the best?
