The main issue with airflow in engine intakes is usually not getting enough air.
If that was the case the all motors would just have huge intakes, throttle bodies and intake valves.
In the mid eighties engine designers learned that they could increase horsepower in certain ranges of engine RPM by tuning intake designs.
Air flowing into an engine is not like a water pipe flowing. The air in the intake is in a constant state of fluctuating pressure. Almost a vibration.
By tuning inlet length to a certain vibration frequency, You can increase intake pressure at that frequency. This can be compared to the resonators on a pipe organ.
Engine designers will often use this to fill in "flat spots"in the power delivery.
By removing the snorkel you could be creating dips in the power curve of your engine. This can be verified with a dyno chart showing dips at certain RPMs.
Then again, they also use these things to quiet induction noise. This might be done at the expense of proper flow.
So, if some one wants to do a proper dyno run with before and after charts, we might be able to see whats actually going on.
Otherwise, do it if you like the noise.
And remember louder doesn't always mean faster.
