I see the Wag Aero heater box has 3 connections: an inlet for the warm air from the Heat Shroud, one outlet to the cabin and another outlet to dump the warm air away from the cabin when the cabin heater/vent is switched off.
The Piper (PA-12) heater box has 4 "connections" an inlet for the warm air from the heat shroud, an inlet for cold air from a vent on the bottom of the lower cowl and an outlet to the cabin. Warm air is dumped away from the cabin when the heater is off, through a hole in the wall of the warm air inlet connection, which releases the warm air into the lower plenum area when the heater is off
Questions:
I have an original PA-12 box and based on the feedback to this question will either:
I'm looking forward to the experiences and opinions
Thanks!!!

Questions:
- Which box is recommended when either are choices?
- Does anyone use the Piper heater box for fresh/unheated air?
- How "warm" is the air from the heat shroud via the box?
I have an original PA-12 box and based on the feedback to this question will either:
- Connect it as per the Piper Parts book (although mount it to the firewall)
- Modify it to just use 3 outlets as per the Wag Aero box
- Buy a stainless steel Wag Aero box
I'm looking forward to the experiences and opinions
Thanks!!!
