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.
save your money
put the money you were gonna spend on that MAF and just get a SD tune
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.
