Just bought a used banshee and it came with NGK B9EVX plug's $8.25 a piece. I'm wondering is it worth the extra money to replace with the same platinum plugs or just reg. B9ES. Thanks in advance.

 

I don' think it is worth the money. However, depending on how you ride, I would bump the range up to a 8 or even as high as 7. I personally like 8's in my pump gas banshee. For the rest of the plug, I like the B8EG plugs. They are almost unfoulable. The center electrode is small and makes a precise spark kernel.
