NGK Iridiums DCPR7EIX & DCPR8EIX (Part Numbers)
Figured I'd share what the part numbers are of the NGK Iridium plugs most commonly used in the sportster from what i've read.
DCPR7EIX - factory interchange with a 7 heat range, stock replacement upgrade plug.
DCPR8EIX - Same plug as above but 1 Step colder!
Also, I took the original factory Harley plugs and decided to Side Gap them, which is unshrouding the center electrode to expose the flame kernel better.
I'm gonna install these in a little bit and go for a ride. This is just an experiment on my own bike. Plus, I'm skeptic yet optimistic on what will happen since I already have DCPR7EIX plugs installed.
So those who will say nothing will happen, please read above again...lol.
Factory Spark plug with Side Gap mod. Gapped to .039

Also, making sure to gap the iridiums correctly is sometimes overlooked as some people are worried about breaking the electrode. Its pretty simple, just by using some small needle nose pliers and some feeler gauges.
I don't really like those coin shaped plug gappers.

Seems like most people who've had issues with iridiums are carbed bikes. At least thats what i've gathered from reading on the forums.
