In an RX-7, what is the best spark plug to get? Are NGKs noticeably different from boschs? Would NGKs help my high end power at all?

they don't "add" power, but if you have crappy ones to start with, ones that can't funtion at high rpm very well, then you will gain power.

I believe there was someone on the other forum that tested the platinum vs. regular NGK on a MSD 6a, and the test result were that the platinum was like 10 more hp or something like that.

10 hp! that's hard to believe.... platinum plugs are just supposed to last longer and that's it.
