Anybody using the NGK 6046 DCPR7EIX Iridium Spark Plugs? I've read some great reviews on them and decided to try them out, just waiting for them to arrive from CVP.
Do`t know about the NGK`s. But I know at least one Member who uses the Denso Iridium`s.
Plan on trying them myself.

I've used the NGK DCPR7EIX before.
Close second to the Denso IXU22, but a lot easier to find in my area.

Thanks for the info, I'll try to find the Denso and grab a pair of those also.

Kainam is who I got the idea for the Denso. Will give them a try first subject to availability.
I know my local Autozone carries the NGK.
Will have to see who around here stocks Denso.
I checked on the web to see if my local Auto Zone carried the NGK, but it wash't listed thats why I ordered them from CVP…when I get chance I'll stop by my local Auto Zone and ask them.
 
Probably wont notice any difference unless you are running a high compression motor.
If you are running a high enough compression that you need to close the gap on the plug to ignite the combustion, the Denso wont have to be closed as much.

Has to do with the diameter of the electrode.
The smaller the electrode, the less voltage needed to create a spark for a given gap.

Denso Iridium is the smallest diameter available (0.4mm), next in line is the NGK IX Iridium (0.6mm).

NGK specified that they come pre-gapped at 0.40" and state NOT to change the gap or it would ruin the plug. I don't have any engine work done to the bike, but I'll throw them in aways since I've already ordered 2 sets. From what I've read their supposed to give an easier start/stronger spark…I guess I'll find out when they get here. At $8.00 each it can't hurt to try them, and I do change my plugs every year anyway so its not a waste for me.
Thanks!
 
The Iridium plugs should be good for 30,000 miles or more.

Yes, I know even the H-D 6R12's are good for thousands of miles, but I'm a real fanatic when it comes to the maintenance on my bike so I change everything regularly. I even did my neck/rocker bearings at 10K even though they weren't in need of changing. It keeps me busy and my bike is always up to par, so why not. :)

Could you come "visit" me, I have tools and Manuals/parts books . :)
