air bridge questions:
Trivial HP gain (if any) but i'm curious if aftermarket air bridges (aka power ducts) have any effect on airflow.
i haven't taken apart a stock air bridge but from what it looks like ont he outside, the cross-sectional area appears to remain constant throughout the bridge (a design that would maintain air velocity)
do power ducts do anything to get more air?

The stock airbridge was designed to quite the sound of the air intake. Aftermarket airbridges in the vast majority of engines are for cosmetics. Some of the early carbon fibre ones were know to crack at the bottom from either excessive heat/rubbing/quality. I have not heard anything bad about later styles.

I have read some articles that say the stock air bridge causes turbulence in the air flow, thereby reducing it. Of course when your in the business of selling intakes this is really "big news", even if its inconsequential to the engine output.
If you can get one cheap...why not. I'd never spend the $250 BPP wants for a new Powerduct, but I found one included with a Vortex intake and a MAF for under $200 (and then I sold the MAF).
Just keep looking...
