I took mine off as the 2WDW ECU tune is for no snorkel.  Without a tune I would leave it, as the factory fueling is done with the snorkel.  Cutting it and leaving the bottom part on might increase the intake sound without affecting the airflow much if that is what your are after.  Cutting the bottom part off might increase airflow as all the air does not have to travel to nearly the bottom of the airbox first, which will affect the fueling.

I agree with mjh, I'm running no snorkel and stock air filter with the 2WDW tune.

 

If i remember correctly I found someone on the forum who had thoroughly studied it and determined that cutting the snorkel made airflow worse if it did anything. 

 

So either snorkel on with no tune or snorkel off with tune
