Default Speed density replace MAF

Does anyone here know what size pipe I can use to replace the MAF? I am wiring in an IAT sensor instead of my 5 wire maf. I want to pull the MAF out and replace it with a piece of pipe, but am not sure what to go out and by.

If it's a one-way trip you can just hog the hell out
of the MAF and nobody'll be the wiser. Gut it out
to the shell.

I'm pretty sure I used a piece of 3" pvc that measures 3.5" on the outside.

I will have to look into the PVC, but if I want some Aluminum tube it looks like I have to order it. Thanks for the info folks.

Or direct port nitrous kit with a standalone. Not to mention the loud exhaust. I am not worried about hiding if I have a MAF or not. I really do not want to destroy the 120+ dollar piece if I can replace it with a 10 dollar piece of pipe.

Replace the MAF with 3" pipe, then tuck the MAF cable and connector out of the way.

You need the pipe to be 3.5" long, 3" inlet and 3.5" outlet
