I like how the OP keeps saying he was convinced to return it to stock. yet when you look at the hks plugs that the pics are shown, it obviously was not. Anyone else miss this? I've kept up with this entire tread, and it's turned into nothing but a broken record....poor me, it wasn't my fault. Get over it, what's done is done and you have no proof, only speculation. There is more speculation about your car and your stories than there is AA at this point. You're well beyond the point of diminishing returns, and I'm out.
None of this info would keep me from buying an AA product, it is merely speculations and assumptions at best.
