What's the pipe in lower intake?


New Member
Just purchased a trickflow intake and trying to find out what this pipe is on the old lower and if I need it on the new one.



Bypass the heater core....Great Scott Batman ...What Now??? I did that same thing during the summer time with my 96 Grand Marquis with the 4.6.... It had the electric HVAC controls and it always blew warm air out the foot wells unless the A/C was on...That solved the problem....

That's what I figured it was for. Is there a specific name for it? I want to get a newer one since everything else is new on my engine.

And to remove the heater tube you loosen the bottom hex closest to the manifold. It will spin inside the top part of the hard lines.
