Remove Air Intake Hose = Deeper/Louder Sound

Hey guys, so i found that by removing number #12 plastic "hose" piece in the picture, effectively disconnecting the cold air front intake, the car sounds MUCH louder and meaner.



I was just wondering if this could do any other damage that i may not be aware of? Obviously since the #12 piece of "hose" is no longer there, once the engine warms up, it will be sucking up hotter air from the engine bay.

Apart from decrease in performance, could this be bad for the car, and could it mess up MAF readings and cause the ECU to do funny things?

I would assume you would get better performance while the engine is still cold due to the less restrictive air intake? However, when the engine warms up, you see the opposite from what i have seen.

Thoughts? Basically I just want to know if it could have damaging effects.. As the car has no temperature gauge, i can't see if things are getting too hot..

Thanks
