The 3000 pipe had a dull gray look and, after the recent engine work for a leaking exhaust manifold, a few greasy fingerprints as well.  I would love to have it powder coated, but I plan to replace it eventually with hard lines.  I also needed to come up with some type of new isolators.  My stock ones had eroded away to nothing.  I guess the isolators keep the engine heat from transferring directly to the 3000 pipe.

After a trip to the local hardware superstore, I found some off the shelf parts that led me to believe I could assemble all the pieces I needed to make a cool air in duct through the front bumper.  I found a piece that is part of a rain gutter that goes from a 3x4 inch rectangular hole into a 4 inch round one.  A 4 inch dryer hose fits perfectly onto the front of the factory air intake tube.  Using two pieces of hardwood, a piano hinge, a piece of heavy flat steel and some clamps I made a metal bender.  It works pretty good for bends over 1 inch and up to 90 degrees.  The bender will allow me to make a metal tunnel to go through the bumper and I will fill in and smooth the cut through the bumper fascia.  I have included the paper templates of the parts I made so it will be easier to duplicate my work- tunnel front part 1, tunnel front part 2, tunnel back.

I drilled a small pilot hole centered horizontally with the factory air in tube and vertically with the flat part of the bumper fascia through the fascia and into the metal bumper.  I then removed the bumper and scribed another 4 1/8 x 2 1/8 inch rectangle onto the metal centered around the pilot hole.  I used a large bit to drill out the corners being sure to go all the way through the metal bumper front and back.  With a cutting wheel, I joined these drilled holes. 

With this done, I removed the metal bumper.  I took a piece of heavy paper, folded it into the hole in the metal bumper, drew pencil lines around the outside of it and along the line where the pieces overlapped, added some tabs for mounting, and used this to transcribe lines onto a 12" x 18" piece of sheet steel.  After cutting the steel I used my homemade bender to fold it into the shape needed for my bumper tunnel.  I used pop rivets to hold it in place.  Two of the back tabs I left unfolded so that I could use them to attach the rain gutter piece onto the inside of the bumper. 

There is a horizontal piece of plastic on the gutter adapter that I cut out.  I did this hoping that any water droplets would run along the bottom of the intake, collect here and drip off and out of the air stream.  I used ordinary dryer hose clamps to attach the hose.  See part 2.
