Selling a used treadstone intercooler. Works great and supports up to 1000 HP. Just took it off of my car this past weekend for a new custom setup. Wanting to get $215 shipped for it. This intercooler sells for 399+shipping new. TRV25 Series Intercooler - TREADSTONE PERFORMANCE It is the opposite facing end tanks version, very similar to the procharger intercoolers. I gained 20 RWHP with no other changes using this intercooler over the ebay horizontal core 31x12x3" intercooler.
