Re: Shorter and longer runner lengths. This dual-length manifold ("link to" fixed)...

is similar to ours, if not quite in configuration, but at least in function (electronically activated butterflies).
I haven't quite figured out how this one works yet, i.e., can't quite visualize how it works in long path, but the plenum appears to extend down in between the low-speed runners.
I thought it was interesting because:
a.) the lid carries the T/B flange which could really be located to point in any direction;
b.) the lid flange looks generous for an assured seal; and
c.) Even though I'd guess this engine doesn't lack for low-end grunt, this after-market manifold has longish primaries, similar to ours (perhaps shorter); and short secondaries, obviously shorter than ours; the combination purpose-built to hopefully raise and yet still widen the power-band; <i>without sacrificing the bottom-end;</i><ul><li><a href="http://www.prager-gmbh.de/Hersteller/B/BBKcatalog.pdf">1996-2004 4.6 2v Mustang Dual-Stage Intake Manifold...</a></li></ul>
