Automatic warm air intake update

[joecvt]

An update to the automatic warm air intake. In the last two months it
has been pretty cold in New Hampshire (the lowest temp so far is 16F)
and I have a Radio Shack remote temp sensor in the air cleaner to check
the temps inside. On the highway I'm able to get to 70F still but I noticed
on back roads the temp only goes up to 60F-63F. My guess is that the
throttle is opening a smaller amount on the back roads resulting in not
much warm air flow through the heated pipe causing the pipe to cool off
more than the highway speeds. So I took it all apart and insulated the
piping more and routed the pipe a different way. I also took off the heat
shield and made a hole and screwed in an opening for the warm air pipe.
This should be a better setup than my last attempt but time will tell. The
average mileage has gone down from 62-64 to 58-59 ...Still not to bad.
Here are some pics of the new setup.
From the vacuum valve to the battery and behind the engine.
From behind the engine to the cat.

You seem to have used a 2 inch EMT (Electrical Metal Tubing) connector normally used to connect to an electrical box
You have used it to connect to the heat shield of the cat. Very good idea!

Yves M., You are absolutely correct about connector (except 1 1/2 inch).
I was able to screw on the thin lock nut that usually comes with them.
There is a nut on the other side as well to hold the connector tight. The
only thing I had to do is drill two new holes on the shield to adjust for the
gap between the opening and the cat. My heat shield was not rusted yet
so I decided to paint it and the connector with high temp black paint. That
was about 8,000 miles ago and the picture was just taken a few days ago
so it seems like its holding up well.

Thanks for your response...You know your stuff!
