A long while back I remember seeing a post for someone selling FMIC covers. The cover sealed the top portion of the intercooler and radiator to prevent air from escaping the top.

Similar to the one in the pic.

I tried doing a search but can't seem to find the link. Thanks in advance for the help.

 

cant help with a link , but it looks simple enough to be custom made by a metal worker /tin- smit ?.

 

I suppose, but you've never seen me with a cutter.

Thanks!
