The pipe that runs between the snorkel and the actual airbox has at least 3 90 degree bends. As well, it has a pretty narrow cross section.
I had to do some significant mods (like get rid of the convertible top and the rain trays), but I've got a cone air filter and the MAF now located in a box outside of the engine compartment, just inside of the air intake. Using Dash Command, one improvement I regularly see is that incoming air is only a few degrees warmer than the ambient air temp. With the airbox/MAF inside the engine compartment, you'll get readings significantly higher.
