My air box is out in this photo because I was changing the filter and MAF sensor.
Leading evidence: 'Replace filter and maf sensor' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, The most frequently discussed action is 'Replace filter and maf sensor' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.
Source reports, not a diagnosis or a success probability. Counts refer to discussions and can overlap.

You get more sound - yes but in my opinion (and the quoted literature) you start changing variables that are designed to work together to get maximum performance.

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Just curious, I noticed on my 02 996 4S the airbox has a (fake) carbon fiber plug. I've seen on other cars a plastic pipe that runs off this. The tube to the MAF (I think that's it) is red too, not black. What's the deal? The red looks sort of silly in a sea of black.
Fake carbon fiber plug sounds like a Fabspeed plug.
Very expensive for what it is.
Red hose might be from various manufactures.
From cheap eBay to quality ones made by the same companies that make inlets for Turbos.
My car came with this mod, too. It gives you more intake noise above 3k RPM.
I love the way my car sounds - it's almost like all 6 cylinders come together to make a musical chord.
My air box is out in this photo because I was changing the filter and MAF sensor. But you can see that instead of the black Y-shaped pipe, I have the orange silicone tube and a cap over the secondary air outlet. Mine says it�s from Schnell, but there are lots of manufacturers making these in different colors.
I found an ever so slight reduction in power from this mod... So I went back to stock. There is documentation that the Helmholtz muffler box smooths out the air flow so the MAF can get a better reading. YRMV
Interesting. I hadn�t heard that. I�ve never had the original pipe, so I have nothing to compare it to. Maybe I�ll try to find a used one cheap and swap it out for a while.
We had this discussion already remember?? Haha
