Is it really worth putting a Cold Air Intake on 370z and what HP gains

Logically speaking, I think you're right. But just how small are these particles you're talking about? How much more pass through the after market ones than the stock ones? and what kind of damage are we talking? Negligible or enough to cause issues in the long run? Do you have any evidence to back up this statement? I've always put aftermarket intakes on my cars and I've never had any internal issues. I think there is more to it than just that, if so K&N would have been out of business a long time ago.
