would you guys rather have iridium plugs or change out multi-ground copper plugs more frequently??...i know that Honda calls for iridium plugs...but new plugs are always better than old plugs...the copper are alot cheaper too and conduct electricty better

 

Stick with the iridium that Honda recommends

 

+1 OEM.
I'm always trying to pinch a $ here and there toobut don't be cheap.[:@] Spark plugs aren't the items you want to be skimpin on.

 

i just changed the plugs in my bike yesterday, and there wer old copper plugs in it, and they turned black, im pretty sure it was b/c they couldnt conduct electricity as well as the new ones i put in which are the new iridium2x's by NGK. i popped those bad boys in and for the first time in a long time my bike fired right up the first time i pressed the button....i am very pleased with the new iridium 2x plugs and i highly recommend them.

+ i only paid 30 bucks from summit racing

 

Another problem solved by using the recommended part.

I know that many here have used copper, but keep in mind that you WILL be changing them more frequently. If you're a constant tinkerer, go for the copper. If you'd rather do it once a year or two, iridium.

 

just wanted to throw this out there ADVANCE AUTO sells the same NGK iridium plugs for $8 apiece. HONDA charges you almost $30 EACH.

 

That must be store specific because I can't find NGK iridiums for my bike at Advance, AutoZone, or NAPA here.

 

OE on my bike is not Iridium, but I put some in there when I bought the bike. The advantage is not that they work better, but that they last longer. In fact, if the carbs aren't screwed up, I will probably never have to change the plugs again. (and if I do, it will probably be at least several years)

BTW, Advance Auto sells the CR9EHIX (I think that's the number) Iridium plugs for less than $7 each. -For the older CBR600s

 

i never knew they had diffrent plugs i need to step my knowledge up

 

napa sells them.
