I've noticed a lot of promotion for the S/S heater box.  If I hadn't already installed the Van's model,  I would definitely spring for the fancy job.  



However, mine is already installed and sealed, so I am pondering if it would be worth the expense and effort to replace it vs the law of diminishing returns.



I understand the science of varying melting points of aluminum vs SS, however, there is inherently a bunch of aluminum forward of the firewall, including the very rivets that hold the firewall together.  What I am thinking right now is when everything is installed on the hot side of the firewall to coat it and the heater box with some type of fire suppressing coating which to me seems cheaper and more effective than just replacing the box itself.  What am I missing?



Comments or suggestions appreciated.

Mine were installed and sealed and that's when I decided I wanted the stainless version.



It really wasn't that bad to pop them off, clean up the area and reseal the SS boxes.



Glad I did it.

Myron;

I took mine off for the SS, not hard to do. The issue would be resolved 

using some fire barrier cream at every opening in the firewall, If you can 

find a way to assure the vents are closed and sealed than leave it alone but 

the SS have a much better seal than I ever could get from the Vans ones.. 

There is a lip on them that deflects any forced air from slipping into the 

inlets. I mentioned before about the forced heat gun and then there was the 

shop vac suggestions of ways to test the air coming in when forced through a 

SCAT, do that with your vents if you can't get it to stop air from coming in 

than the SS from Plane innovations will give you that advantage. For me, 

being in So California I don't need any more hot air coming into the cabin 

in the summer so this was more important to me than fire protection.

It is the largest and most vulnerable opening in your firewall. Not to criticize Vans (their job is to get a kit out there at a reasonable price), but do you want to be your life on a flimsy aluminum valve.



For those still building - the EXCHANGE cost is about $100.



For me it is a no-brainer - replace with SS...
