I'll have to check out these Bosch W6DC.Bosch W6DC
They seem to have a wide heat range application as they cross reference with Champion N6, 7, 8, and 9 spark plugs.

- Denso IW22 for dual coils
- Denso VW22 for dual output single coil
Was pretty sure you would get a full spectrum of replies on the question or spark plugs. Surprised no one suggested Delco as that has had followers in the past here. Myself I’ve used NGK and Champion with good results. Currently NGK in my ‘72 using TriSpark classic ignition, Emgo 6v coils, solid copper wires and NGK resistor plug caps.Hi a simple request Ngk, Champion or Bosch, what are your thoughts.
The kickback i have been fighting is just like the timing is to far advanced. This is the first ign. System i have had this issue with. The rita’s pazon sure fire and trispark never gave this issue.
The rita is an old design that is power hungry and does not play well with dual tower coils and is no longer supported. The pazon sure fire is an analog ign and as such does not have idle stabilization. And lastly if you have followed my posts with 3 trispark failures and the 3rd not even lasting as long as a rear tire along 3 stators costing me $150.00 each on top if the original cost it is why i am where i am at now.And........? Why aren't you using one of the 3 mentioned which never give you a kick back?
@Fast Eddie what Jim said!!!
But for simpletons like me, this is how I see it:
With a dual output single coil, one spark fires from ground electrode to centre electrode, and the other spark fires the other way from centre electrode to ground electrode.
So for these coils, the precious metal tip on only one surface will only be beneficial on one side.
The VW22 has an iridium centre electrode and platinum ground electrode.
The IW22 has an iridium centre electrode and nickel plated ground electrode (same as plug housing) so is ideal if you are running two coils.
Where the hell have I been? I never knew, So are the NGK plugs dual polarity?
Yes, a good plug.I'll have to check out these Bosch W6DC.

So you're suggesting the VW22 for dual tower coils?

I use Champions N7yc in mine, I have tried NGK's a few different times but they always fail in a couple days. Champions will last a couple years and then I replace them, keeping the old ones for spares because they are still good.
I think a lot has to do with your ignition system.....I'm using points.
NGK now makes Ruthenium spark plugs if you want the best available dual polarity plug.
But since the spark plugs in a Norton are normally changed out within 10,000 miles the extreme life plug options are usually just a waist of money.
[but I do run the Denso iridium/platinum combos in my bike]
