Write up - How to remove your MAF
Well, have not seen any post on how people actually remove the MAF from there car, even though quite a few have. So, I figured I would post up my method. It works good, was cheap, almost looks factory, and can be put back to stock no problems.
Edit: this is for guys running/wanting to run speed density
I got the supplies from the local Ace hardware store, and the total was only $13. All you need is a 4" fernco coupler (in plumbing section), which came with 2 hose clamps and a piece of 4" white plastic pipe (this was for a dryer vent).
Procedure:
1 - Remove regular intake setup (lid to TB coupler hose)
2 - Remove MAF from lid (this was PITA on mine, damn near broke my lid getting that damn MAF off it!)
3 - Now if you have a normal lid (ie not the 85 mm TSP lid) you can simply take the GM rubber connector that goes between the MAF and the TB and turn it around and put it on you lid. I had to heat mine up slightly to soften the rubber, but it fits great on the lid.
4 - Then, take your white plastic pipe and cut it to about 2" in length. This will serve as a way to join the GM connector and your fernco piece.
5 - Next, the trickiest part is cutting the fernco coupler at an angle. Luckily I got it pretty darn close first try. But you want to cut it at about 15 degree angle to mate up easily to the TB.
6 - Once that is done proceed to put stuff together, then put it on the car. The cool thing about the white plastic pipe is that you can look inside it and see if the seal is good where the band clamps are. If you see black all around you have a good seal. I also chose to wrap some electrical tape around the MAF connector not being used to keep it from dangling there.

And yes, the computer will run SD. It is the backup in case of a MAF failure.

I gotta give props, without this thread I wouldn't have even thought of this combo.
I did the full fernco which is actually 2 fernco tubes, hacked together with a coupler, similar to how this is done.
But like has been mentioned, it is really firm and doesn't flex for anything.
I think this setup is a really happy medium, and if you polish up the fernco and stock bellows, it can look pretty slick as well.
Great idea, and nice writeup.

IMO Speed Density is pointless unless you are pushing more airflow than the MAf can read or your cam causes so much reversion in the intake that it is screwing up the MAF readings.
