I must admit that the 80 series filter unit is the Schizl. It is huge, has a nugget trap in the bottom that really works, and the OEM elements are washable. I am thinking about coating my housing with ceramic heat resistant coating to reduce my intake temps in the SC. I'm playing around with a couple of ideas to help cool it down without having to go to a full blown intercooler. Johnthanks inkpot, its the same case as the 80 series i believe its just a nicer top for my app.
