As most of you know, I am installing a ram air duct in my bumper (like Deedub/ VS8/ Etc). Well I removed the front bumper to take off the 'hose piece' and Im having trouble taking it off. There also seems to be a sensor maybe attached to it. I honestly just thought it was a hose and figured it would be easy to take off, didnt realize it was going to be this difficult.

I attempted to remove it as youll be able to tell from the pic but no luck

Please see the pic so you can understand what I am talking about, I circled the piece in Red and the 'sensor' in yellow.

Is this piece okay to be removed and if so what do I do with the piece circled in yellow.

 

There is a vac line that attaches to the lower tray part of the stock intake...

" Sensor" is the VFAD vac actuator

 

okay, can I remove it or what should I do?

 

Yeh remove it - and disconnect the VFAD solenoid side of that under the UIM

 

make sure you CAP the vacuum nipple underneath the UIM...

 

Don't forget to plug the vac line...it is usually done at the intake manifold...most any auto parts store has the caps for that.

 

Kane, thanks for the advice and sorry to sound like a noob, but what do you mean by this last sentece, whats the UIM

 

its the yellow cap ... don't remember the size but i think they are color coded... I put in my rb air ram a little while back.

I removed all of the lines back to the manifold and capped it there. You don't have to take off the bumper reenforcement.. it fits with some pressure if you are using the rb as well.

 

Im not using the RB duct, Im putting a hole in my bumper (like deedub) for the ram air.

So your saying I need to take the whole vac line out and cap it?

Again sorry for being such a noob with this stuff

 

upper intake manifold.. you'll see as you work your way back into the engine bay with the vacuum hose it'll lead to the UIM where you have to cap the vacuum nipple.

 

aahhh, okay makes sense. Thank you for explaining it to me. So I need to go to autozone to get one of these caps huh?

 

that or may have a few laying around..

those types of things but you're probably going to need something a bit smaller than 1/4''.. get to it and feel it.. you'll know then.

 

yeah anyting that fits will work good....

 

Yeah cap the line; at the Solenoid under the intake manifold.

I guess you could cap it at the VFAD itself and just leave all the piping there... but I would take it all out.

 

Okay, just got back from my garage, got it all out. lol, I know I sound like a tool but I dont have a friggin light and my garage light isnt that bright, I cant see that well in my engine bay. Anyone got a pic of where this line ends to make my life a tiny bit easier..?

Also, will there be any side effects to the absense of this vac line? Cel, idling issues?

 

Nothing.

The vfad (variable fresh air duct) is their only for noise abatement at lower rpms.

 

Follow this:

 

what if i didnt cap the vacuum line when i installed mine...what will happen?

 

Vacuum leak FTL...

 

so is this where I cap it or did I misunderstand kane?

 

It'll work there.... really anywhere you cap it is fine. If you want to clean it up some go all the way to the bank of solenoids that are under the intake manfold on the oil fill plastic piece. Along with the one that runs to the bottom of the intake manifold.

 

great thanks for the help guys.
