Is an air intake resonator necessary?
Take out any bolt that holds the resonator assembly in place (you can see several in the picture, they’re all 10mm) and pull the mess out. The only problem is removing the white piece, but I’ve done it three times, so it can be done. once this is done, you have some options as to what to do next:
Since these pressure waves are essentially sound, giving them a place to expend their energy before exiting the air filter box ends up dampening the intake noise and quieting the engine. Thus, the resonator helps to make the engine paradoxically quieter and more powerful.
The Resonator. Adding an expansion chamber to the intake tube forces air coming back out of the engine to slow down to fill the cavity, thus expending a great deal of its energy and slowing the pressure wave reversion.
This is the hideous resonator assembly Honda has to use to keep the VTEC engine quiet enough for the normal driver. Thought you only needed a muffler on the exhaust?
The resonator delete can sometimes improve your overall horsepower rating if there is heavy buildup within your vehicle’s exhaust system. Your goal is to create a little back pressure on the engine to create better efficiencies, but not create something that is close to a blockage.
Even though resonators work to eliminate annoying hums and droning sounds, they can be removed so you can achieve a different sound note. Deleting the resonator will also make your vehicle lighter. Where a muffler delete might not be legal, you usually don’t have to worry about that with a resonator delete.
All you have to do is take off the bumper and two trim clips and it’s easy to get to with a mere socket wrench (10mm). Once off you just pull out the big old box and you’re done. I also had my hood popped open and removed that piece to help the intake of air in front of the battery.
When you take out the exhaust resonator and replace it with a pipe, the back pressure can be affected. It will reduce the efficiency of your car and you might end up consuming more fuel while also hearing a louder noise. Consequently, this leads to achieving peak performance and saving fuel.

While dampening the sound of the engine is one of the purposes of the air intake resonator, it is not the primary purpose. The primary purpose of the air intake resonator is to inhibit pressure wave harmonics, which causes air pressure in the engine and restricts the amount of airflow through the RPM spectrum.
