Varley are you planning on going from the throttle body then?
Imho I think that's unnecessary as the Zed already has a good intake tube there which a lot of G35 owners buy as it is better than what is on the G35 (look at Z tube mod).
Personally I'd be looking at going from the MAF onwards. That way all you'll need is a MAF top hat adapter, followed by a straight silicone hose, aluminium hose joiner, then a 90 degree bend hose, aluminium hose joiner & filter.
Will look something similar to this then...
What do you think?
