Last summer I drove from TX to RI and back with a PVC home brew installed.
Had a digital thermometer probe in the intake right by the TB, Found that
once I was moving the temp. rise was only 3-4 degrees over the abenit air
temp. When stopped the air temp to the TB rose quickly to above 119.0. The
digital thermometer high-end limit was 119.0. I do have the PVC pipe wrapped
with foam and metal tape to help keep down the heat transfer from the engine
heat. I have about 10,000 miles on the home brew with no troubles at all with
it. This just shows that the PVC pipe is subjected to a wide temp change and
should this be a concern? I need to stop by the shop that installed my
cat-back system (pipe rubbing against axle) I'll find out what it would cost
to get a 3"pipe to replace the PVC.

<< OK,has anyone figured out,that as you are driving,the cooler air,entering
the pipe,will keep it cool enough?..
Is this just for the homemade ones,or does this affect the same ones
currently selling on E-bay?
Im going to go look at the factory hose tubing that runs from the
Restrictive air box to the GenIII Air Hat...now,why couldnt this be
used?...why noy just buy some of this,or go to a junk yard.
Also,i'm going to look at some plumbing shops..If it can handle hot water up
to 140 degrees,then.....
Somebody respond to this...
My kit from E-bay arrives on Thursday..
