I don't think you need that box any more. It looks as though you have some sort of ISR mod which I thought removed that portion of the intake. I would remove it.

Hemholtz Resonator
Basically it is there to reduce the sound of the air induction system. Some people do not like the air sucking sound. Some manufactures in recent years have actually gone the other way. They have added resonators and tubing running into the passenger compartment, calling them sound enhancement tubes. Designed to give the driver a more tuned engine sound on performance vehicles. It is not a critical part, and can be deleted/removed without any changes to performance. Just make sure the induction system is sealed properly.

Its the internet, everything is true! Just kidding by the way. Its physics, it is there for creature comfort.
Hemholtz Resonators serve no mechanical function. Personally I try and leave things as stock as possible, but sometimes on these older trucks finding replacement plastic parts can be difficult.
Most smog legal aftermarket intake systems like K and N induction systems eliminate the resonators. Most people buying them want the performance, and want to hear the induction systems. Same reason why Ford put the sound enhancement tubes on the 5.0 mustangs. Most of the people that drive them want the sound. Just like a high end lexus will have some crazy resonator systems on them, most people that buy those want smooth, quiet luxury.
I always encourage others to do research before making decisions. Just don't take the forums as gospel.

These folks http://www.brighthubengineering.com/...ic-efficiency/ and http://www.ehow.com/info_12156112_ai...onator-do.html agree that it's physics -- the physics of volumetric efficiency. (Which is what I would guess you could call "mechanical function.")
I'm not surprised that someone (like K&N) making a "universal" induction system would not be able to tune a resonator for every possible application. Makers of universal O2 sensors don't include the connector. But that doesn't mean the connector serves no function.
I find it hard to believe that the engineers in Tokyo were putting parts onto this truck just for funsies. If someone runs a careful dyno before-and-after removing the resonator, I'll pay attention to that. On the other hand, I don't really care what K&N is doing.
Of course, YMMV. Considering that we are all talking about trucks 20+ years old, the efficiency gain of a resonator would probably be lost in the general wear and tear.
