Do I really need this resonator box? #4049903 03/27/16 12:15 AM

Intake air hose on my Camry broke, so I ordered a new Dorman one. There's a resonator box underneath it with a hose that goes to it, the hose had a hole. I couldn't find an aftermarket replacement hose, so I called the dealership. They want $76 plus tax for the hose. Not gonna happen for a beater-commuter car.

I went to Home Depot and bought a 1-1/4" plug and a hose clamp for $3, fits perfect. Took out the resonator box, is it really necessary? What does it do, I'm guessing sound dampening? I drove it around the block, power is the same and so is sound, maybe a tiny bit louder, but I really don't think so.

The resonator is purely for sound dampening. It will not hurt power or economy one bit.

Yep, it's just a muffler. I would have done exactly what you did and enjoy a little more growl out of the engine at WOT.

What's that box on the left side of the 1st picture where the spark plug wires are going over ?

You mean the valve cover?

WRONG. They are also used to tune the intake air impulse to increase midrange torque per toyota.

Doubt you'll notice it without a dyno.

Agreed, that is part of a system to reduce resonance as KIngCake said. It will cause no issues for your daily driver/beater. Ed

It looks like the plug might be long enough to extend into the intake tube. If so you might want to trim it back, you don't need any added restrictions or turbulence. As said these boxes are used to tune in or out resonant frequencies in the intake impulse as well as noise control. You'll lose a little something without it, Toyota went to some trouble to gain that wee bit of torque or mpg. Aftermarket intake tubes eliminate these boxes (K&N, Airaid, etc) all the time and claim gains but they're also smoothing the pipe by eliminating the connection.

the plug doesn't go much further past the hose clamp, still plenty of room before it impedes air flow in the tube.

I'll keep an eye on power/noise/fuel economy and see if I notice a difference.

It will run fine without the resonator, but you will lose power and volumetric efficiency at certain rpms. The pressure wave caused by the intake valves closing will now slow down the intake air.

I want to know how what box does anything for power.

There are effects to increase the V.E on N.A engines. As with most tuning, this Intake tuning can be a compromise and only truly effective over a certain RPM range, but picking a choosing the design to fit in around the engine, the "boost" given can be used to smooth out the output over the engine.
Tuning can be done via the length of the intake runners, and their size. Long thin intake runners will speed up the gas velocity and the momentum of the fast moving air will help pack the cylinder full even as the intake valve is closing. This will boost power at lower engine speeds, but the thin runner design will restrict airflow at high speeds. Tuning and resonance of the pipework will also help.
As the engine sucks in air, there are pulses of high and low pressure. The tuning is designed use these pulses of pressure to get more into a cylinder, by adjusting the size and length of the intake. This effect is known as Helmholtz Resonance. The resonance effect will only work in a given intake size as a specific RPM range, so this can either be used to remove a flat spot, add extra torque in lower RPMs where most day to day driving occurs, or a variable length Intake system can be used to provide two resonant effects at different RPM ranges. An example of this is the BMW DISA flap in some manifolds.
