Then with that done, The engine coolant temps should remain normal and I should have the same great 5k RPM roar of the engine coming from the intake.
Am I right or is there something Im missing here?
Im willing to hack-up my snorkel for the sake of experimentation since I am currently driving without it.
I would appreciate any opinions or suggestions before I decide to under take this task.

Hi,
Sorry, but you're missing something here.
Your coolant temp has absolutely nothing to do with the intake air. The coolant temp is the result of extracting heat from the block and cylinder heads produced by friction and combustion and the system's ability to shed this heat to atmosphere through the radiator fins.
If you've noticed an increase in temps, it is purely coincidental. Your ambient temps may be hotter than you remember, or you may simply be noticing it more.
With the new, cool, sound, you may be into the
WOW pedal more than you were before resulting in higher than previous avg. RPMs and consequently more BTU's produced.
You may also have sucked up some debris - leaves, cigarette butts, gravel, insects, and the like into your intakes blocking some of the airflow through the radiator(s).
You can certainly modify your snorkle if you choose, but, it's a waste of a good part because you won't see any improvement to the temps as a result. If you did, again, that would merely be coincidental.
Besides, the Temp gauge in the Boxster is so inaccurate (as a result of vague and inexact graduations) that's it's difficult (or impossible) to determine a rise in temp of a few degrees, even if you marked the dialface to indicate where the temp needle was, there's some degree of variation to this every time you run the car, even though the temps are relatively the same.
The snorkle is indeed a noise abatement device, but it has nothing to do with the coolant temps you see at the dash. If it did, you'd be more likely to experience reduced temps because of the increased airflow to the intake. Hope this helps...
Happy Motoring!... Jim'99
