Usually I know what I want before I get to parts store. Went and got some stuff for oil change and tuneup. Went to pick up a plug and theres three available.

One stock ....ngk

Now heres the other two burn better and have the split on bottom for better spark. Still NGK.

Anyone use the later two?

Pros.....cons? A big not use warning?

I just went with stock.......which was on the bike and also stated in manual. If theres a benefit or more pros then Ill pick up the other plug later maybe.

Thanks!

I have never noticed any benefits from running more expensive plugs in anything unless the factory calls for them. Stock NGK's have always worked great for me. I change mine out once a year. Not because it needs it but just because I feel like I should for some reason.

I use NGK BR8ES. A touch hotter than the stock BR9. LIke SS, I notice no difference from a high dollar plug in my bike. The NGK's are cheap, and they work great!

Many have reported, when everything else is perfect (carburation, etc), that the fine wire rare element NGK plugs offer a slight improvement in throttle response. B8EIX, B8EGV. I always just run the BR8ES, and buy them by the box. All bikes, sleds, etc use them.

I will say I've tried cross-referenced B8 plugs by champion, and they sucked, but work great in a mag-fired kart motor. Seems jap CDIs really like Jap plugs. NipponDenso equivalent to B8EIX, worked great.

Always been using a NGK BR8ES
