Black box removal?

[frapjap]

I've had an aftermarket intake for a while now and want to free up some engine bay space. That little black box that I have capped off from the intake has to go. I was going to go at it alone, but upon closer inspection, it comes from the exhaust, up to the box, then there is a sensor under the box, and 2 small tubes that make their way around the front, over the radiator, and into a small splitter-like thing, then into the throttle body. I'm not sure what I need to do to remove this, and what can be removed. I've searched, but haven't found anything useful other than "cap it off." Thanks.

do a search for "AIV removal"

pretty much you just take everything out of there and cap off anything you can't remove. Unplug any electrical connections and just tape them up so they don't short on anything.

You're car will run better without that silly contraption on it. Mine revved a little faster too, a little less bogging.

Yeah, I second removing it. It helped me in the same way. Anyway, the two small tubes are tied into the vacuum system, and the bigger one comes from the exhaust. So, make sure you seal all of them well. I put small screws with epoxy into the vacuum lines, and a large bolt and screw clamps (salvaged from AIV) for the exhaust tube. The sensor-like thing, that is solenoid that operates the AIV, you can just unplug it and remove that with the box.

If you want it to be "pretty," you can trace the vacuum tubes back the TB and cut them there and hook them together. You can get a plug (probably from a nissan dealer) that seals the hole in the header that leads to the AIV. I just hooked all the loose items to something else in the bay, looks ok to me.

Thanks for the help and what to search for. I didnt know the system was called AIV. Thanks to everyone who pointed me the right way.

Theres no hole in the header, its in the downpipe. To fix that take the pipe from the aiv to the downpipe off, cut it off, use put 2 nickels where the hole was and screw the bunge (I guess...the little twisty thing that holds the aiv pipe to the downpipe back on) Viola, aiv is gone.

Zero-S, thats a lot for how to seal that little downpipe hole. I planned on using the nickle method, as thats what I did for my EGR, but wasn't sure. Now I have everything to do the job, someone should make a 240 faq for little things like the air filter adapter, aiv removal, egr, lsd, stock swaps. They're there if you search, but sometimes ya just get the wrong thing, ya know?
