I've never really liked all the extra tubing, sharp bends, and overall restriction added by a snorkel.
In the past, I've thought that removing or relocating the ABS modulator to the factory air filter location would give me room to have short intake with an in-line air filter in almost a straight shot, full throttle body diameter, right to a single bend up the A pillar. Now, it may require more body work than a Mantec or similar, and perhaps even some material removed from the hood (possibly not, if I let it dip a bit) but it makes more sense to see if it's even possible first.
The sticking point for the intake itself is just how closely a MAFS, throttle body, and air filter can be in relation to one another. It's still going to measure airflow, but it'll be hotter and closer to the residue that ends up collecting around the throttle body. Also, the air filter will be much closer to that area. This is all assuming the space makes it possible.
I haven't really seen anything mentioning the drawbacks or potential failures associated with a MAFS that close to the throttle body. I know they don't like contamination at all. I suppose the possibility is there for a small power increase, but the objective is really to avoid a drop in power and intake efficiency.
There's also the issue of relocating that modulator. That's a lot of brake tubing, but so long as it's hard I don't see an issue. If it's removed entirely, it becomes a different problem. Then there's keeping rain out of it, but there are a few ways to mitigate that; it's worth actually building a test setup to be sure, but it should be possible.
What about that MAFS and filter being so close to each other and the engine, though; and more directly exposed to the heads and exhaust manifolds? Heat shields are obvious, but that doesn't change the issue of contamination and overall temperature in the area.
If it's possible and probably reliable, I'd essentially have a "one bend" cold intake solution, rather than a "six bend" solution with three 90s in the mix and a corrugated section as well. Seems to me it would eliminate quite a few drawbacks if possible.
Cheers,
