Im putting a jdm H22 in my 92 lude.... My buddy helpin me prys on the engine a little to line up a mount and he smashed the little black box under the intake manifold(vacuum tank??) do i need this or can i bypass it??? thx in advance
 
Its where the iab hooks up but its cheap just got off the phone with honda parts its less than $40 for the tank
 
Or save yourself $40....hook up the wiring harness to the box, then run the vacuum line directly from the IAB solenoid to the intake manifold. I did it, and it worked fine.
 
it still wont function correctly though, the box builds up vacuum to open the secondaries and the ecu tells the solenoid when to open up so the vacuum opens them up.
 
The default for the IABs is open. most people disconnenct the vacuum from it any ways.
