Factory Airbox And Afm's?

[spec-V]

Hey guys, just a quick question, I don't want to use pofilters and I want to retain the factory airbox..

My goal is 400awhp. I know the factory AFM's won't handle this (or will they?).. How do I go about keeping the factory airbox as they are all one peice are they not?

I have been told you can use Rb25 AFM's for applications under 450hp in lieu of Z32's ? Can you just remove them from the GTR housing and retro fit?

Cheers!

Nismo AFM's mate. Direct fit, stock piping airbox, the works.

Buy them from perfectrun - cheapest in all of the internet at the moment.

Yep Nismo AFMs is the way to go, support something like 775hp as a pair. I'm in same dilemma, keeping stock airbox but need 280kw+

Or, if you are changing the ECU as well, better off just switching over to a MAP sensor and you saved yourself the $$$ and you never have to worry about AFM's again.
