Anyways, you can't make a MAF too big, or it won't read poop. Plus the cool part is you could use two MAFs for error correction on each other. Much more efficient.

Here are some pics of the new concept GTO. I would like to point out that this intake appears to be a production plastic intake, but it does not appear to be an LS2 intake.
