4 MAF adapter? Is there some reason why this 4 piece with a bolt in MAF sensor would not be a good choice?
I went through the expense of the 102 TB and 102 FAST intake, so I dont want to choke it with a small MAF, and the 100MM MAF sensors I have seen are $250+ Is there some reason this 4 adapter tube solution is not good? (with an LS7 5 wire MAF sensor with IAT)
Im just wondering why anyone would spend $250+ on the other ones, if there was not some reason they were better.
BTW, aslo going with a procharger, less than 10 lbs boost (and tuner I have talked to says we can do speed density, but using the MAF would be better if we can)

Are you using a blade-type MAF or a tube-type? The adapter you are looking at is for the drop-in blade type. If you have a 102mm TB, that is already 4" dia. Just use a rubber elbow and a straight tube with a drop-in MAF fitting on it, and use a 4" filter. No adapters needed. Check out the Spectre site for all kinds of plumbing parts for air intakes. You can roll your own for not a lot of $$$$.
BTW, the blade-type is what comes on most Gen IV engines. Gen III used screened-tube-type MAFs

I'm building custom, so I can use what I want.
it started life as an LS1 from a 98 Z28 but it is going into a procharged 63 corvette.
My specific question is about using a stock blade type in a tube like this one VS the $250+ 100mm MAF sensors.
so far I have yet to find a reason anyone would spend so much on one, when this other option (tube and blade type) is SOOOO much cheaper. Often you get what you pay for, but if I'm paying more for something I like to at least know why.

As I said, check Spectre's website for intake plumbing. I don't think you need that adapter as it's used for adapting to different tube sizes, and all you need is 4" tubing WITH the blade MAF slot and a 4" filter
I have that same part, along with a FAST 102 and NW 102 DBW, and it works fine. Uses the LS3 card-type sensor, of course, nothing a competent tuner can't handle. mine is with an n/a application, not boost.

From what I have read/heard, many think reading actual values real time, should always be better than trying to look them up from a predefined table, and tune easier. I also asked the shop I will likely have tune it, and they said, I could go either way, but it would be a little better to use the MAF, so I'm mainly going by people who should know far more about it than me. Plus, it was not a huge amount of money, and if for some reason I change my mind later, it can just be programmed without it, but adding it in later if I left it out now, might be more challenging.

The one you linked to is garbage. The plastic piece on mine warped very badly after about 200 miles which caused the o-ring to no longer seal. I ended up getting a "blank" 4" Spectre tube (https://www.spectreperformance.com/s...aspx?prod=9709) and an aluminum Spectre MAF mount (https://www.spectreperformance.com/s...x?prod=9924011).
The MAF mount was also garbage. The first one I got was machined all wrong, so I returned it for another one. The second one was a little better, but I still had to re-machine it. The rectangular step where the MAF gasket seats was machined too deep for the gasket to compress and the bottom curved surface was machined crooked so the MAF card would never have been straight in the tube. I then welded it to the 4" tube and ended up with something that actually works. I will never buy another Spectre part again! Junk! I did the re-machining and welding because I needed to get the car running and was sick of shipping junk parts back and forth. If I had more time, I would have went with another company.

That's just how my particular tuner likes to do it... And just to clarify, I have nothing against a MAF. At all. I was just pointing out it's an option.
You have to tune with the MAF first anyway.... Then you just turn it off. The O2's take it from there, along with the IAT. Get the restriction out of the path, I say. On my 01 SS, just an NA setup, It was orth like 9/7 to the tire. Throttle response was crisper as well.
