I've got a 70mm Pro-Flow mass air meter. Demon is right though to get the best gains go with an open element intake. However, with the 70 or 75 mm MAF you will get rid of the stock center bar that can cause turbulent air to enter the intake manifold. This way the open element and the mass air meter work together to make more power. As for just a MAF, I don't know if the power gains would be anything spectacular but you would pick up some.
