Yamaha VMAX HPDI 250. What spark plugs??

[CrankerZ]

I need to replace my spark plugs in my engine. Does anyone know what size plugs it needs??

That info should be on the specificatations page of your manual. If you don't have a manual, you can download one from the pinned post about manuals at the top of this Yamaha page.

I believe you need NGK BKR6EKU but verify in the manul or with someone else.
If you're not sure pop a plug out of your motor it will be written on it.

The 7 eku and 6 eku can be run in that motor. NGK plug.

Dont get them from the dealer, cheaper at Boaters World, about 2 or3 bucks each.
