Is there any minimum distance the MAF needs to be from the throttle body? Asking because I am planning a "stack" (maf attached to throttle body and filter attached to maf, no pipes) just need a new hood.

The piping in an intake system plays a major role on how the air flows in the engine. If you take the piping off then there is no swirl effect causing a lot of turbulance going into the throttle body. This isnt a good thing for fuel burning. As far as the maf there really isnt a minimum distance. There are a few gm cars that has the maf attached to the throttle body for better throttle response. The pipe going into the maf has to be straight atleast 6 inches. Meaning there cant be a bend and then the maf 2 inches after. Turbulance and it will cause irratic readings. Hope this helps
