Searched and saw a few threads on spark plugs but most of the post are over a year old.

whats the latest and greatest spark plug out today available for the KLX250?


Just wanted to go ahead and order another plug or two while im doing some online shopping.

ETA

I saw an advertisement for this E3 plug on the sponsor banner. anyone try those yet?

 

Plugs are plugs.

I like NGK V power.
They're cheap, and good, but so are many others.

 

Nothing has really changed in this area. Most would agree that the Iridium plug of the proper heat range and model...it was spec'd in those posts you saw...is probably the best plug design. Many would also argue that a relatively simple 4-stroke engine like the KLX doesn't benefit to any noticeable degree with the installation of a precious metal, high falootin' plug. What's in my KLX?...one of those high falootin' Iridium plugs. Why?...it makes me warm and fuzzy when my head hits the pillow at night.

 

hey if it gives me a %.000001 advantage Im SOLD!

 

I have the iridium plug and the bike start great. I had iridium plugs in my car for 100,000 miles and took them out to replace them and they were still good. The iridium in the klx should last forever.

 

No advantage, but they will last longer.

 

Don't buy Bosch, only plugs I've had trouble with. Best luck with NGK through the years.

 

lol...
