Ok, so I want to do a shorter intake, where the air will be pulled from a hole (think t2 hole above the intercooler) in the hood (not pulling air from inside the bay; I do have a plan on how to seal it off from the rest of the bay, as well as how to keep water from being sucked into the intake). I have a question about intake length...



Basically, I plan to put the cone filter directly after the intake elbow after doing the AFM->hot wire MAF mod. The stock AFM is down near the end of the intake piping, and I was wondering if having it so much closer to the TB and the rest of the intake would cause any calculation issues w/the ECU? Logically I would think not because if the air is moving w/X velocity at the AFM then it's going almost the same speed at the area where I would plan to place the MAF sensor.



Oh, also...the only reason I though of using the elbow is because I don't know what else could fit that to adapt to a standard circle like at the opposite end without fabbing one myself. I could FG one if people really think it would give an improvement to airflow, since the air doesn't have to try and cut the corner at all at that point...

thanks for the response...ok, well i figured i'd do it since by that point im going to do my own FG hood, so i can mod it to my heart's content to get what im looking for

i had mine come straight off the tb and the filter was where the charcoal canister was.



i cut the na elbow to almost straight and stretched a home depot pvc coupler over it and the afm



free revs faster, and the intake is louder.



didnt notice any power difference, but if its getting colder air i imagine its doing something.



i also had the back of my hood spaced up so air did get in there to it.
