To answer your question....Yes, I have actually used them. Quite a bit actually, and always ended up being more satisied with NGKs.
I just do not think they are worth the money. Just my opinion.
I think Champions are worse though... other than the Truck plugs. I used to earn a living removing Champion Plugs from GM cars... they where a warranty issue, and was SOP at the GM dealership I worked at to remove them. I have worked most of my life professionaly as a Tech.... so I speak from my learnings, and not hearsay.
If you like em, and have good luck with them, thats great.
As to chiseling them out... yeah, somebody probably was not looking at them often enough.... peaking at the plugs every so often is a good thing.

Dr. Dyno said:I keep hearing a lot of people bashing the "Shitfires" but I wonder if any of these people have actually used them, or are these opinions just based on heresay?
As someone who's actually used them (and still am), I think I'm more qualified to speak about them than those who blindly bash them.
My first set of regular Splitfires lasted 40k miles and were still working fine when I replaced them. The gap between the electrodes had increased to over 0.080" and they were still firing. How many ordinary plugs can maintain that sort of performance after 40k miles?
I'm now 67k miles into my current set of triple-platinum plugs and they're still performing flawlessly, as are my 107k mile old Splitfire dual-core plug wires.
Shitfire? I don't think so. Forget about dyno tests. Longevity is the name of the game as far as Splitfires go. If anybody has to chisel the plugs out of the head, it's probably because they've not needed to inspect them for a few years because they haven't caused any problem. You might even find cobwebs growing on them by the time you need to change them.
