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

If your going to run the stock air system , then you may as well just stick with the stock paper element or just the simple fram oem filters. These flat slided oiled filters are even more prone to getting dirt transfered to intake side of the filter after cleaning, than the round cone type. Like I said before in the original beginning of the post, you really want throw away your old air cleaner after 3k-5K miles and replace if with a new oem unit. I do it with every oil change, as they are so cheap.

Another note with these oiled air filters is that they flow more air mainly due to their larger screen mesh or filter material hole size or MICRON size. Meaning the actual diameter of a dust particle which can pass thru the filter mesh or media.

Interesting to note that the cheaper paper or disposable filters have superior dirt filtration when compared to the high price cleanable filters.

Your ultimate goal with the air filter is to protect your engine life span.

Another issue is that these complicated air intake sysytems may actually void the factory waranty, if you put one on it should be one that can be put completely back to stock after instally it if any issues develope.
