For the lower cowl with the snorkel, the snorkel is at the front of a wide channel in the bottom of the lower cowl that ends on the aft side with a big opening where this portion of the cowl sits about 3.5" below the lower firewall flange. It looks from what I can see on the plans that this just gets left open? I.e. that you can look through the snorkel and see through out this wide gap in the back of the lower cowl. Is this correct?
