I know many of you are like " aww man this newbie is asking another stupid question" but hear me out. I searched for this and couldnt find a viable solution. Heres my question. My friend gave me some piping to put in to replace my stock intake, im gonna use a bbk pipe, and a K&N tapered cone air filter.



The top pic is of what he gave me.

My question is, i have no idea what that thing i circled is. I dont know if its important or not, because i have seen other sc's with redone intakes without that part, but im not sure if i have rewire something or what. Please Help. All help is appreciated.

 

Those are vacume lines, and yes you need them

 

Big -----> IAC valve
small --->PS air control valve

 

So all i would need to do is find a tube like this with the little vacuum extension near the end?? And the rest would be fine?

 

That’s what I did

Note: the car above is a SC300 just incase u didn’t know, and the intake was for a GS300. Check out my Sig. for the DIY Link.

 

You will need the big one for sure especially for that big V8. The little one you can replace with a breather.

 

Technically you dont need them for the car to run. Your check engine light will just go on and you need to plug the valves with breathers.

 

O yeah i understood that it was a SC300, i just wanted to know if it would be the same for my car. Thank you for all ya'lls help. Much Obliged.
