We're selling this heat exchanger that came off of one of our customer's cars. It is an SSI, thick flange, LEFT side and has O2 bung. It will fit a 911 from '80->'89. I tried to reference the part number that's on it to see who the manufacturer is (SSI 938170) and came up with nothing. It is in great shape and the only reason we're replacing it is because the customer wants to match the thin flanged RIGHT side. We're asking $400 (+ shipping) for it since it is in such nice shape. Please let me know if you have any questions!
Thanks,
Aaron Heinlein
