As the title says, which spark plugs do you run with a supercharger at about 6lbs of non-intercooled boost? I've read threads that say NGK TR6, but they were all at least two years old, and I can't find those particular plugs on any of the auto shops' websites (NAPA, Advanced, Auto Zone, etc.). Are they under a different part name/number now? Or if not, where can I find them?
Is there some other kind of plug that I can use (i.e. heat range, gap size, material, etc.)? I'd rather not use a copper plug on account of having to change it at least once a year, but if that is absolutely the best thing then I guess I can deal with it.
