I was ambivalent about it, until I spoke with Jaay (whose posts are all over this forum). So I removed the snorkel. I agree with what he told me: “Just look at the snorkel.” There is a very significant narrowing at the end closest to the side air vent. I just got the snorkel and traced the inside of both ends as best I could, just to take a look. Without getting out my protractor and brushing up on my geometry, I would guess that there is about a 40-50% reduction in size from the large end compared to the small end.
Now, how many people spend all lots of cash to increase the diameter of the air intake system in order to improve airflow. You cannot convince me that the small end of the snorkel does not constrict airflow, even if only a little.
Did I notice a difference in performance? Not sure. I like to think I did, but it could all be in my head… in any case, I'm keeping it out.
