Responses like this aren't going to bring very many people to your lawsuit.
I feel your pain, I really do. I just got done helicoiling spark plugs on my neon thanks to **** threads on spark plugs that I didn't realize were Chinese when I torqued em in.
But from what I asked earlier, there's no tolerance called out. A judge likely doesn't know if 150cc is a lot different from 176cc or if it's normal to have that kind of variance, and there's not really a standard for this stuff. It doesn't say they're AT LEAST XXXcc....
If they promised 400hp on ANY engine build on any dyno, you'd have more of a case, but what are the damages here? How much did this affect you? I can port those intakes through to water and they'll technically be huge in volume, but does that mean it'll be a solid performer?
Any suit involving false advertising has to be able to define what the damages are, or you're going home to write a check for their legal fees.
So what are the damages, exactly? Didn't make power? Damaged your engine? Probed your anus?
Just saying, they do it, because they can.
