Air Breather Hose On My Comanche

[BrandonLH95]

Hi everyone! i just couldnt help to find out what the name of the slinky looking hose that runs from my air filter box into the intake, if someone could give me the name of that it would be greatly appreciated :doh:

My model is a 1988 Jeep Comanche Pioneer 2.5l I4

Actually it goes from your exhaust manifold, the aluminum piece, to the front of the air box. It provides (correction: it is SUPPOSED to provide) warm air to the intake when the engine is cold. When the engine warms up, the vac servo on the air box is SUPPOSED to close off, so you get direct cold or as cold as you're going to get. If the servo or the vac line fails you just get hot, hot air.

 

I have no idea what it's called. It might be a good idea in theory but it's a.) such a flimsy hose b.) dependent on a very weak part of the vacuum system that's usually broken or missing anyway. IMHO it's useless since almost every single one I see at the junkyard is either missing or shredded.

yea well its has a couple of holes in it where it enters the exhaust and dad thought well it needs to be replaced because it may be sucking up dirty air and there is no point in the air filter if you get what I'm sayin

The hose doesn't suck in air. It directs radiant hot air from the manifold area to the air box with the intent of using warm air in cold climates. The manifold end of the hose is attached with a bracket with a open end. The only reason mine is still there is because of the "visual inspection" regarding emissions in CA. The smog tech even told me it serves no purpose in Southern climates but has to be attached to pass inspection.

Just ditch it, it's useless.

The intake sucks the radiant hot air in thru the front of the airbox. The hot air is just there. That's how useless it is.

 

Go to a different smog shop...I have never been dinged for that...mine has been gone for 7-8 years. It's not even present on any years after 1990 AFAIK.
