Pioneer 2 air box intake

[hondabob]

The air box intake is pretty good. One picture is from under the bed showing its sealed good from the rear wheel area. The intake is out board in back of the passenger seat.

Wonder so many chambers in the intake pipe.

Those chambers remind me of the ol 250r intake boot. Never really got the concept of those chambers

The chambers are actually resonators. When an intake valve closes rapidly the air flowing toward the engine in the intake tube is actually forced backward away from the engine and without these resonators you audibly hear a boom type sound with every valve cycle. These chambers give the air a place to go for a split second until the valve opens again thus reducing that sound. You typically wouldn't hear it at higher rpms but certainly do at lower ones like idle. They also help the air flow in be smoother since the air blowing back can hide in these chambers instead of just colliding with the air that is on the way in. This helps power , fuel economy, smoothness of engine running, ect.
