black box under intake manifold???

[93accordtuner]

i noticed that there is a black box bolted to the bottom of my friends F22A6 EX intake manifold and not on mine.... i just ordered a F22A6 IM to swap it out for the dual runners but im not sure if it comes with that blakc box on it.... what exactly is it/ do? do i need it?? and what is it called so if it doesnt come with one i can look for one??? thanks

That is the Intake Air Bypass vacuum box and solenoid. It controls engine vacuum for the IAB valve when the ECU sees the car exceed 5200 RPM. My solenoid was bad when I bought the car and I noticed more torque after I fixed it.

Basically opens the secondaries in the IM when it hits a certain RPM. Thats the easiest explanation.

well damn it seems like i need that to even make the a6 manifold work... anybody know where to get one???

best bet would be the junkyard or egay. Remember, you need to have an ECU that will control the IAB system or it will be useless. Also, you'll have to run the wires to the ECU too.

Technically you dont. If you dont install it just stays open all the time which you lose low end and eat more gas if i remember correctly. I need to go look at my a6 mani again.

Don't leave it open. The last guy is right, you can, but it KILLS (like brutally rapes and murders) your mileage and low end (I lost like 3mpg and would bog below 2,500RPM. It's really bad.). I watched Ebay for mine for ages and never found one. I finally got a guy to go to a junkyard by him to get one because I couldn't find one at my local junkyards. When I took the vaccum lines off it though, the damn things must have been fused to it somehow or another, because it broke the part of the solenoid that the lines go on. If you think you might be able to figure a way to get it to work though (I was thinking a small enough plastic vaccum line cut and fiberglassed on would do) I can sell you that one. I got another one when I was lucky enough to find a CB7 with an A6 at a junkyard. I can also see if I can find another. BTW, don't go to the dealer. That damn tank and solenoid combo are damn near $200

You can also get one from an h23 or h22. Its a black box. Does anyone have a pic of where the wires connect to the black box. I only have 2 prongs and not an actual connector. I wanna see how it hooks up on a stock setup.
