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

I changed mine at the recommended 15k miles and while yes, it was dirty on the outside the filter still looked good on the inside. I'll also say that when it was dirty, that's compared to a new filter, otherwise it wasn't as dirty as what I would have expected for the enviroment that my car has been in. Our stock engine bay is pretty well sealed. I honestly doubt you have much to wory about if keeping the stock airboxes. If you are so worried about it, just stick with the OEM filters and intake setup. I would love to see an independent study comparing OEM filters to various aftermarket companies. I could see how early designs of reusable airfilters wouldn't be as good compared to paper filters, but I think with all the advances in technology this gap has definitely closed if not become nonexistent.
