Hey guys I have a few 6061 billet aluminum inline water coolers I made up for sale for $20 shipped if any one is interested. These are 2 1/2" long and have 9 cooling fins. They will fit any 3/4 radiator hose. I can also make longer ones if anyone would like them. Just pm me with the length you would like and I will get you a quote. If your interested in any inline water coolers just pm me and I'll get back to you. Thanks
