How's this for stealthy:




Even though l have an AEM fitted, agreed. The benefits are so marginal, they're barely worth any dollar spent on a CAI system. I just don't see any negatives to remove the vfad, especially since Mazdaspeed did with their setup.

 

That stealthy setup is awesome! Mazdaspeed removing the VFAD does give it's removal a lot more credit and points toward it being there purely to keep the car quiet. Still, I do think that if it did anything at all someone would have some dyno evidence by now..
