z32 maf? apexi afc? apexi power intake?

[Fenvy]

I Am not too sure about all this. I did the nessassary research but I am still confused

1) what is the use of upgrading to the z32 maf?2) can I get the z32 maf without the afc?3) why is it also that I see people mate the afc with the z32?4) what's wrong with the maf from sr20det?5) i just want an apexi power intake, 507-n004 alone is good enough right?

1. to adjust airflow signal to the ecu. 2. yes you can, but you need to retune your ecu to run a z32 mafor run a stand alone unit.3. more cost effective alternative and its easier to be locally tuned.4. nothing really, if your gonna stay stock. but if your gonna upgrade to bigger injectors/turbos or boosting more. u need an enging management or piggyback like an afc to compensate with extra fuel and with extra fuel u need more air. the signal given by the stock maf is limited.5. yes, thats only an air cone filter
