Stock air box all the way
Z32 AFM also bolts straight up to it - half the time people don't even know what they are looking at so they won't realise its a Z32 AFM
Just use the stock air box with a paper filter man, you really can't go wrong
I have had to go back to an Apexi power intake filter as my standard air box doesn't fit with my new piping setup (intake and cooler) which really sucks to be honest
I'm just waiting for the day I get pulled over and raped!
One weekend when I am free I might attempt to make the air box fit, it is possible but just takes time to do it
Plenty of people making high power figures on standard air box - why wouldn't you use it?
