Different from the dual-resonance intake that the factory supplied in your S4?

That looks nice, but has _some_ idling/drivability issues from the MAF not having a clean, linear, EVEN airflow over the hotwire, like the OEM setup does.

I had one, I saw saw it with a sharktuner myself, and other report of the same.

A honeycomb above the MAP helps a lot, with evening that out.

The problem is air flows at different velocities around the bends to the maf.

The stock layout the required air better falls to the maf at even velocity. The hotwire sees this.

IIRC, Roger is/was offering a version of that intake. Hopefully others will chime in with availability if none are available new.

I had one of these on an 88 S4 and had zero drive-ability issues. I still have it because I removed it before I sold the car on.
