Just curious what the purpose of this box is that sits below the battery and is connected to the airbox. I thought this was the resonator that I always hear about but that is the thinner plastic box between the airbox and manifold, correct? Is it safe to remove the box below the battery? Thanks.

 

i think it is kinda supposed to help get more air to the air box but im not sure

 

Intake resonator/air storage thingy.

 

Once the stock intake goes, it doesn't need to be there. I didn't know about it until I tried to install my injen and it wasn't fitting ecause of that piece. Took it out, realized it does not serve any purpose
