Question: what is at the end of the snorkle? Is there a filter or is it just an open tube?
i didnt close it I removed the whole darn thing leaving a 2" (guessing) opening in the airbox (under the filter mind you - meaning no unfiltered air to the engine) - i allowed the air box to breath more / an there is nothing at the end of the snorkel its where the snorkel runs into the airbox that you will find the "valve" (for lack of a better term)
