box next to oem air filter box with pigtail plug

[accordlove]

what is it? it has a hose that runs to the intake manifold and looks like it has a wastegate in it lol

The black vacuum box on the inside of the fender on top of the two plastic intake pipes for the air cleaner box? The "waste gate" in the lower pipe is closed up to about 3500 rpm so that air is taken in only through the upper pipe and the lower pipe is open to the resonator inside the fender to reduce intake noise. Above 3500 rpm, the valve in the lower pipe opens to allow both pipes to feed the filter box.

so if i want to delete it i can?

[Fleetw00d]

Yes. I simply removed the box and plugged the vacuum line (or cap it at the manifold). This leaves both intake pipes to the filter box open all the time. I never bothered to remove the resonator inside the fender (doing so may make it more prone to pulling water in when splashing through puddles unless you block the two holes for the resonator).

I think at least the 93 LX/DX eliminated this box and simply run a single intake pipe with the lower one only connected to the resonator. On my wagon I installed a lower one with intake to reduce the restriction feeding the filter box.

I took everything out and left the factory filter box in. Still looks stock but sounds and breathes much better. I just need to get a K&N factory filter to gain another mpg or two.

Thanks for the info man, the filter box has to be completely submerged in water to bog the engine out (my cold air intake got caught in a flash flood one year in my 99 accord lol). speaking of that car, it didnt have this lil box on it either and my last cb7 must've had it deleted because this is the first time ive seen one.

thats what im doing too and i noticed the random box in my OP. Thanks man.

k so i deleted it today and used the small hose that was on it an a zip tie to plug the port on the IM, took all the piping from the air box out, hosed and cleaned all the old dirt and leaves out from behind the headlight and under the battery and cleaned out the air filter and it sounds cool af! like i have a short ram intake but probably way better!

this is all on my new $350 project cb7 that i'll make a ride thread for once the ricer paint job is gone....

At one time I cut about a 3 inch hole in the bottom of the filter box, but my wife didn't like the growl.

lol i HAVE to do this. My girl friend actually thinks it sounds cool the way it is now. it still has oem exhaust but i can tell some sections have been re done with slightly bigger piping and im pretty sure i have an EX muffler. i took my exhaust mani heat shield off the 1st day i drove it home and found a crack on port 4 i think is the one lol on the far left looking at the engine where they usually crack. so she sounds kinda ricey at the moment lol

Can the pigtail be removed all together? Ive yet to find where it leads into, anyone fully delete it?

[steelbluesleepR]

you don't want to go just removing wires for no reason.

[PDXxCB7x503]

Im more or less just curious as to where they lead off into.. Like just single power, ground and control wires or something like that. excuse me if this doesn't make sense im just starting to actually dig in an learn about electrical and such.

they go to your ecu so it can tell that lil valve to open or close at certain rpms, and im not sure what will happen if you splice them and jump them, just do what i, and im sure most have done, and tuck the connector off somewhere behind the head light.

The other option is to simply plug the vacuum line to the box and leave it connected electrically.
