are they any good?

 

No

 

what are good brands of spark plugs?

 

NGK and Bosch plats.

 

I found some NGK iridium IV, any good?

 

see civil in this thread a nice change.

they are fine people say that iridium is only for longevity of the plug... meaning they might last a bit longer than plats but same amount of spark... that is what people say... I don't know though.

 

i ride with ngk iridiums; they're good. ngk is honda's plug from the factory isn't it?

 

are u saying that they are for longevity more then performance or just overall they last longer.

 

yeah the iridium should last u longer... they perform the same despite their claims of +1 or +2 hp... or if they even do that.

All I remember is that they cost more and might not be worth it, depending on the increase in the price, ur call... like I said before its ur money do what u want with it.

 

cool im gettin them about 6 bucks a piece

 

Denso Iridium >*

 

DOH... yeah those too

 

DENSO Iridiums..

 

those are better then iridium IV?
