CR9E vs CR8E Spark Plugs
I bought/installed the wrong plugs by mistake. I didn't have an owners manual at the time I changed my plugs which was the next day I bought my bike.
The previous owner used some DENSO plugs so I brought those to a store to ask whats they are in NGK. They gave me NGK CR8E which I bought then installed. Then I just recently found out the stock ones are CR9E.
I've read from other posts here that it might work as they are "hotter" plugs but I'd like to know what are the effects if I continue using the CR8E? The pros and cons of running "hotter" plugs.
Also, I'm living in a tropical country(hotter climate) and I'm only using 95 RON fuel. I've read lower octane fuel burns at higher temp so using hotter plus would make sense but please do correct me if I'm wrong.
