I found this black box under my intake manifold all cracked up. it seems to be a vacuum box and could have been the cause of my vacuum leek issue. basically wtf is it do i need it? Motor is a 94 GSR

 

its your iab box.

 

and what does it do and do i need it

 

its for your secondaries, just get another one

 

what if i removed them can i just take it out the system and not worry about it?

 

bump need answer

 

you can, but the the IAB wouldnt work and you MAY throw a code, im not sure on that one.

 

ok so if i removed the IAB from my manifold and remove the box ill be fine?

depending on your mods; you will loose power in the low-mid range

 

Well ive already removed them from the manifold and the box is fuxord so what im asking basically can i just loop the vacuum lines and be ok? Im running two different ecu's a p30 + p28 since they both dont read IAB's

WHen removing the IABs from the manifold you will lose a few ponies under vtec. but running on a ps28 or p30 ecu you wont notice it. when you get in vtec the high rpm's 6000-8,500 pull alot harder its just like if you got a skunk 2 manifold

 

wow i luv it... vacuum box eh... exactly wat i need to run my secondary
