i have an hks intake, and the 3/4" tube used to go to the airbox. What do i do with that tube now? should i cap it? it looks like to me like a major boost leak.

 

do you have pics?
it is probably for one of the bovs.
are you still running your stock twins?

 

forgot to add: if the 3/4 hose is to the bov, you do not need to connect it to anything. it will now vent directly to the atmosphere instead of your intake box. this results in a louder "whoosh" that many enjoy. I just removed & capped my pfs cold air box so that I get the louder bov noise. silly, but i like it.

 

it's right between the mani and the pipe that goes to the intercooler. i have pics but they are too big. i have a greddy bov with large m2 intercooler.

 

it was the tube that went to the airbox and then to the bumper to like vent or something. i no longer have the stock air box, so what do i do with that tube to the bumper technology

 

If it was the hose that went down underneath the airbox and connected to nothing then throw it out. It is no longer needed with the airbox gone.

 

Yes that hose is just to vent. You can toss it out like he said.

 

if you are talking about the hose that comes all the way from teh fire wall to the airbox, then that hose is for the excess air that the airpump generates to go back to teh airbox to quite it down. withuout some sort of a muffler on there the car will "moooo"

 

This should help.

 

Nice pic jonski!

 

indeed! great pic - helps explain a lot

 

Glad I could help.
