Aftermarket Intake. What Did You Do With The Stock Airbox Vacuum Hoses

[SBpunk]

Just a question. There are a bunch of vacuum hoses going into the air box. Two tiny ones, one that goes all the way back behind the washer fluid and into the firewall plus a couple more I'm sure I'm not thinking of. What did you guys do with all these when you put in aftermarket intake to free up space? I ordered a THOR cowl intake and don't want to screw up my engine. Thanks

One of the big hoses go to the  front CCV/PCV on the valve cover, and the other one (that wraps around the washer bottle and along the firewall) goes to the vacuum canister.  The other two smaller lines operate a vacuum motor used to help it warm up quicker by pulling in hot air off of the exhaust manifold.  Those two aren't near as important so I just capped them off and tucked it somewhere.  The one big line going to the vac can needs to be installed and the other going to the CCV/PCV can be replaced by a small mini cone filter or hooked up to the main intake tube, like below.

Sweet thats what I needed to know! What did you do with the vacuum canister one? I'm guessing just  cap it off also since I don't have emissions testing here

Nvm just saw it in the pic. Damn guess I'll get a T connector since this thor one only has 1 hose intake for the front valve cover hose.

You could do that or you could use a mini cone filter for the valve cover hose and plumb the vac canister hose to the Thor's inlet.

I don't know if this matters to you or not but the line along the firewall is from the fuel evap. canister, not the vacuum canister.

You could do that or you could use a mini cone filter for the valve cover hose and plumb the vac canister hose to the Thor's inlet.

 

 

So use a cone filter for both the front and back valve cover hoses? If I can get away with that great! I'm not even entirely sure what the evap canister does besides keep the smell of gas down a bit.
