I think I’m becoming an old moaner and would like to remove my Apex’I induction kit and replace it with the standard Air Filter box, because of the noise.
I have the induction sitting in a carbon air box with an aluminum hose running all the way up from underneath the right front bumper indicator.

Anyway, I know how to remove all that stuff, but how easy / difficult would it be to reinstall the OEM air box? Is it feasible with the car on the ground? Or does it have to be lifted up or even the side wing removed? Is the plastic duct held by screws inside the wing or does it just attach to the main air box?

If anybody would have a pic somewhere that would be greatly appreciated.

Thanks,

Just fit the airbox. The resonator in the wing is useless anyway.

Thanks for the tip, but doesn't the small curved duct just above the headlight supply air to the resonator?

When removing the resonator, I couldn't figure how air is getting directed onto the air filter, I will have to have a closer look at the assembly this weekend....
Am I right to say that the whole assy. is made of 3 parts? The duct, resonator and airbox? Suppose I absolutely want to have the resonator also refitted, would I have to remove the entire wing of the car, or let's formulate it like this; is the resonator screwed onto something inside the wing or just squeezes fit into place?

I'm just thinking of refitting the whole thingy, maybe I'll sell the car within the next few months or so.

Resonator just deadens the sound. You'll get more air to the filter without.

If you want to re-fit the resonator, you should be able to get it in under the wing (without removing it). Just the reverse of removal.

I had a look at it this weekend, and there's no way of fitting the resonator without either lifting the car or removing the wing.

Just my thought on the use of the resonator. I understand that many people believe that by removing it, it increases power by a slight amount. I would say that by removing it, the air that is supposed to go through the resonator's hoses into the air filter box, will simply be directed into the inside of the wing and will get "lost" in there. I think the big box at the bottom of the resonator acts as an air tank, when sitting in traffic in summer, it helps having the necessary amount of air readily available to be sucked in through the filter by the turbo, thus avoiding heatsoak?

Someone corrects me if i'm wrong, but if one absolutely wants to remove the resonator, it would maybe be more beneficial to replace it with a hose that goes through the two holes on the inner side of the engine compartiment, connecting the small headlight duct to the main airbox.

So, what do the experts think? Good idea to fit a flexible alu-hose instead of the resonator, or just remove it and leave it as is?

Thanks,

As far I know the resonator is their to reduce the noise. The snorkel is fairly useless too.

You'll get more cold air without them both IMO.

And you should be able to refit without removing wing.

The resonator is there to reduce noise as said before and the snorkle combined with the resonator is there to trap water and moisture. Subaru have to make sure that they account for cars that ford rivers etc and avoid sucking water into the engine.

Removing the res and snorkle will not be a problem for your airbox as it will suck air from the wheel arch area. Heat soak will be a problem, whether you have a res/snorkle or not. There will not be enough air in the res plenum to cope with heat soak and that's not why it's there.

There is also 'little' risk of water ingestion unless you are in a very wet area...
