So my block is 18mm, but the 18mm filter selection blows. Im looking for a sandwich adapter, for an oil cooler, that will accept a 3/4" thread filter so I can run something hugegantic. Has anyone seen this before? I suppose I could make my own nipple setup, but Id rather not if its already available. Thoughts? Dan ---

probably going to have to cut two “tubes” and weld in the middle, face each on a lathe and chamfer/tig and maybe spin again in a lathe to ensure it fits through the cooler plate. ---

Ya. I thught of that too. However, I think Im just gona get the biggest 18mm WIX filter I can find and be done with it. Itll be way easier and I wont have to worry about welding etc. Dan
