    Yamaha makes the best Marine engines and they used a quality spark plug like NGK

    Yamaha Corporation has hundreds of thousands of hours developing and perfecting their Marine engines of all kinds. NGK is the spark plug they decided to use. NGK did not buy Yamahas wishes to use their product. I am 68 years old and I have been using NGK spark plugs for 50 years because that long ago NGK was the only plug in a copper core. Champion, Autolite, ACDelco and all the rest we're way behind the performance and quality curve. So when I bought my Waverunner with the 1800 cc engine and it came with NGK plugs, I knew why Yamaha had made the decision to go with a company as reputable as NGK

    Perfect plugs for 2016 FX HO

    These are the plugs I have been using since day 1. You don’t need the high end NGKs or the splitfire type. There are no benefits
