There is a little hose going from the air intake box to the exhaust manifold. What's the impotance of this? My 2.3 didn't have one when I bought it and I was curious as to whether I should replace it or not.
 
all it does is on cold days it sends warm air into the intake from the header. not really needed. I usually just get rid of em as they get to be a pain when trying to tune the vehicle. it helps the motor warm up quicker and idle a little better.

just make sure the flap is closed if you do remove it.

Well, I live in South Florida....Cold days....ha! Anyway, when air is cold aren't the molecules closer together....meaning more air gets into the engine....meaning more power? I understand that its to warm up the engine when it's cold though, just saying. Thanks.

I just capped the vac motor for the flapper

Is that sufficient?

After it's warmmed up, it actually idles better than with it operational
