I am selling my used left & right intercoolers, brackets and air ducts off of my 1990 300ZX Twin Turbo. I removed them several years ago after purchasing upgraded ones. There were NO known issues with these when I replaced them and I would assume they are still in fine working conditions. They are great if you are going back to stock or need to replace a damaged one. I have no need for them and they are just taking up space in my garage now.
