Title: BR9EG or BR8EG KX500
Post by: dans89kx500 on January 17, 2008, 02:47:11 PM
With the 89 KX5 should I run a BR9EG or BR8EG? What is the difference?

Stock bike uses a BR8 heat range.  I would suggest the BR8EIX over the G or V.  Those are old tech and the EIX is the irridium electrode that has proven to outlast anything with the best flame from.  Most new vehicles come with these for a reason.  cam.

8 is hotter than a 9.  G is one upgrade over an S.  V should be the minimum.  Got the bucks run the irridiums like Cam sayzzz....

Is there a difference with plugs even with the same numbers? I found a box of ten B8ES @ Pep Boys for $10 and change, but the plugs seemed to foul easy. I noticed the electrode and the whole bottom of plug was an aluminum-colored silver and my old ones from the bike shop were a copper-color.

I wouldnt waste the money on the EIX... IMO they are no better than a standard ES.... I run B9egv's in all of my bikes

Two plug threads going.... eeekkkk.

Is there a difference with plugs even with the same numbers?

Generally speaking, the numbers represent the heat range and in compatible/matching plugs they mean the same thing.  But, sometimes in a stock bike that is a little old in the top end, people run hotter plugs (8 or 7 which is hotter) to help the ole' betsy to run right and not foul when putt putting around.

Sometimes that is purely manufacturer preference on colors....  sometimes to help identify the plug types (quality in a brand) at a glance or for wow factor....
The electrodes (center and ground prong) materials are the biggest difference in the plug type classes.
