    If you want the best flowing one just remove the MAF and have your engine speed density tuned, otherwise just use the stocker, they flow well.

    LPE has a 100mm MAF (metal body) and there is also a comparable cheaper PowrMaf (composite) at 100mm or you could buy sensor and buy a GM mounting bracket, after-market pre-fabbed tube, or make your own (cut, weld, etc.). There are other options like TSP, SLP, FAST, etc. For the time, effort, money I saved, went with the PowrMaf and it is already setup to change out the gm sensor if it goes bad (new $55 - $100). You also buy the adapter plug from them and change your current wire pins over to that one (which I did...simple...instructions on site) or there are also adapters elsewhere online you can buy as well with your end wired to the PowrMaf end. Retuning will be necessary.

    I know all this is way more than the OP question, but I will also agree with the point that swapping a sensor (MAF or MAP) for power only is not worth it (and only 10+/- mm dia. difference & screen) and the money could go to something with a better dollars to power ratio. I just recently went FI and hit a 12k Hz MAF table limit; the upgraded MAF is one way not the only way (there is a way to cut the resolution in tune in half), to keep the MAF in which case you lose some resolution (512g at 10+k Hz instead of something over 12+k Hz) with an added plus of an upgraded sensor. I plan to experiment with a 2 bar tune (boost tables yeah) and 2 bar MAP sensor next to compare then decide my own preference. I will leave it in the experts hands to argue an SD tune has more power than a MAF tune as I have not found any additional in one vs the other at least NA to date. cheers.
