Purpose of the snorkel is to direct the leaf-blower like air blast straight at the bottom of the air box, letting it fragment there, swirl around then go through the filter.
De-snorkling puts the air blast aimed directly right at the very top edge of your air filter. This puts a physical wind load on that section of the filter, causing rapid dirt fill and premature "filtration failure" of that area of your K&N media.
Removing the air filter door allows air to gracefully enter from all sides, removing most of the wind tunnel effect of the desnorkled closed air box. It allows minimum resistance to maximum air flow and provides the best even use of your filter media.
BUT IT IS NOISY. Noisier, anyway.
