So many plugs, so many choices.

Hey guys, just looking around and having some trouble in finding plugs for the bolt.

I have a 07 xb12r with the full race kit, and I am looking to replace the plugs, and do a full tune up for the season. I have heard of NGK, Iridiums, Harley double platinums and stock.

The question I have is which runs best with what I have and what is difference between stock heat and colder heat range for the Iridiums???

Thanks in advnace guys.

They'll all give a spark, not much to say there. It gets gimmicky beyond that. But the Iridiums are proven to be very foul-resistant, last longer without needing changed, ect. - which comes in handy with our bikes.

Older thread, but it's thoroughly discussed: Spark Plugs thread

LOL, I knew ^that^ one was coming, considered posting it myself. If you're main concern is HP, you got the wrong bike anyway.

I have used all of the aforementioned plugs and fouled all of them but the NGK Iridiums. I put new wires on as well last year when I put in the Iridiums.
