Has anyone ran the NGK Iridium IX DPR8EIX-9 Spakplug in the Raptor 660 ? And if so how did they work for you.
Thanks,

 

i know a guy that was running one in his yz 250 and he said he didnt notice any increase in performance, he said he wouldnt get one again. becuase they are more expensive and they dont do any thing. if you have a good running bike you shouldnt need one. but if you have an older bike that may need all the help for spark that it can get , they might be worth it

 

Run them in my Grizzly. Don't really notice anything. But of course I started running them right at the same time I put the pipe on it, so I wouldn't know it even if there was a difference. They are freakin expensive, I know that.

 

Iridium

My thought was the edges on the tip will stay durable and last longer between changes over standard plug.

 

mine starts easier and feels the same. it might just be a mental scheme to make you thing it runs better. [img]i/expressions/face-icon-small-happy.gif[/img]
its only 7 bucks ive gotten other stupid crap for more than 10 , why not a spark plug and impress your friends with "IRIDIUM" LOL

 

I paid more for the shipping than I did for the plugs. No place around here to get them, had to order it. Damn shipping was like $11 for just 3 spark plugs. Thats freaking pathetic.
