[ATL BRZ]

So who is going to be dropping their front bumper to remove the stock intake snorkel from behind it?

The flowbench testing showed a ~20% improvement in CFM without the snorkel.

To get the most airflow I recommend removing the factory inlet to let the box breathe from the space behind the bumper. It is possible to unbolt the top edge of the bumper and sneak the inlet out very carefully. We designed in a nice smooth velocity stack where it mates to the inlet which netted a couple more hp. By adding the velocity stack and removing the factory inlet, the CFM increased by 20% on the flowbench. I also stuck my hand in through the opening where the airbox breathes from and it is noticably cooler inside the bumper, so we know it is a great source for fresh, cool air.
