What type of spark plugs are you guys using when replacing?

 

ngk iridium. rockauto.com has them for around $10/ea. cheapest place i've seen in awhile.

 

You like them better than the denso plugs...

 

Never used them in the bike. Ngk is OEM, so I go with those.

 

Just wondering, denso was the oem in my 02....I use ngk in the dirt bikes, but was curious if denso was a better plug ...They sure cost more...

 

ngk's here.

 

I'm running the NGK's. I pulled out the Denso's around 10,000 miles.

 

+1...iridium...by NGK...no gappin...install & go..

 

The denso's were OEM.

 

ngk's came in both my 929s. the dealer sold me ngk when i got plugs for it. stupid to buy from them, i know, but that was before the forum and better researched links. i know my first one was serviced there once or twice. stuck with ngk since.
