I want to make a base plate for my air cleaner and use foam to seal it to the hood. I know I can buy plates like this, but I would rather make my own. does anyone know where I could find the foam? I'll probably need something about 3 inches thick.

 

if you want to make a mold around the base hilti was a spray foam for fire stopping that is sold at home depo. might be to ridged though.

 

I was looking for of a "sponge" type foam

 

Get the replacement Moroso air pan foam at Summit or Jegs, it's what I used for mine. Summit part number, MOR-97070

 

if your talkin about the red fireproof stuff hilti makes it dries real hard. the gray stuff dont dry at all, not sure if the gray is made by hilti maybe 3m. either way the brand has nothing to do with the question. google found me this http://www.alibaba.com/product-gs/206174628/fireproof_foam.html

 

thanks guys... the summit stuff is exactly what I was looking for :]
