Just got a bit of a suprise after doing a bit of searching on here. A couple of years ago I bought a fire damaged Z to break for the leather and wheels etc and found it had bigger intercoolers on so I fitted them to my car and thought nothing more about it. I thought they were some cheapo brand that I have never heard about and had thought about selling them cheap and buying some that are made by a fabricator over here in the UK. When I took the bumper off the other day to paint it I noticed the badge says ARC Super Intercooler. So after doing a search on ARC I dont think I will be selling them after all :) Paul
