What spark plug do u use?

cyclepro101 · Jun 12, 2009

Just wondering what spark plug everyone is using, before I go out and buy every model in the NGK series.
I use the BP6HS, I found this much better than the B6HS as the electrode protrudes futher into the head.
I was thinking of going for a cooler plug like a BP8HS.

B5Hs is what I have.

I agree with Joe... Try the 5 first!

I use the B6HS gapped at .035

I found no diff between the 5 & 6 so I went the cooler 6.
I recommend using the BP*** plug though as it seemed to give me much better results than the no protruding elctrode type b***

Just be cautios. You could protrude the plug too far.

I have used champion cj7y when clearance was an issue
(it has a much shorter head)

I use a b7hs, talked to another guy using a b9hs. If you can get away with a colder plug your motor will have more power. You can buy a b7hs at shucks/checker for 2 dollars. Try one. If nothing else you b5 users will have a spare to toss in your bag. GL
