Cold air induction for 87-88 TC's
3/12/00 by Bob Penland
This is a simple modification that goes along with the K&N
cone filter especially well. It solves the problem of the cone only
drawing in hot air from inside the engine compartment.

I found all of this in the heating section of Home Depot.
There are a series of holes in the nose pointing towards the
ground, these are for air pickup to go into the radiator. The black
plastic piece running horizontally on the bottom of the nose it to provide
pressurized air to the nose cavity; thus cooling the car. We are going to
tap into this
Instructions for installing ducting:
- Open hood [don't laugh, some people would get stumped here
:)]
- Feed hose into the nose cavity in front of the radiator

- Snake one end up to oval shaped hole next to the K&N
cone. Make sure not to have any kinks in the hose.
- Using the foil tape, affix the hose to the oval opening in
the frame, pointing as strait as possible at the cone.

- You must slightly bend the 4" - 6" adapter to fit
it in between the bumper cover and the frame. After it's in bend it
back to size.
- Using the foil tape, affix the adapter to the other end of
the hose in the nose cavity. This will serve as the cold air pick-up.

- Place the hose adapter in one of the largest holes towards
the center prefferably the one to the passenger side so the air doesn't have
to travel that far.
- The 6" opening is almost a perfect fit, if it wasn't a
circle. So using the foil tape underneath the car, tape the adapter to
nose, sealing up any holes between the adapter and the plastic.
There you have it, simple cold air induction. Hope that
helps you all.
