cobra mass air flow sensor?
 

here is the link, mass flow sensor

what I want to know is if i get one of these do i have to mod my computer also? I hate the big bulky mass flow sensor it has and would like to open up the intake. and if this wont work then is there another product or way to unrestrict the intake by geting a sensor out of something else?

It says right there in the ad that it only works with a JimWolf ECU.

To get more throughput on a non-turbo Z, you can use a ZX turbo AFM and carefully take out the electronics. Install electronics from a non-turbo AFM into the turbo housing. It will require some simple tuning by adjusting the flap tension.

If you have a turbo Z, then going with an aftermarket computer is the only way to change. There are some that use a MAP sensor instead of an airflow meter. The map sensor detects intake manifold pressure and vaccume. There would be no meters on the intake tubes at all.
