9000 Intercooler from ETS features smooth flowing cast tanks and a highly efficient bar and plate core. The core is 100% vacuum brazed, and features louvered external fins, and a very fine internal fin pack. To attain the maximum efficiency possible, the internal fins are offset and staggered to get every possible air molecule to “scrub” up against an internal fin so that the heat may be transferred to the external fins and carried away from the intercooler. It is this unique design that allows this ETS intercooler to attain an 83% efficiency rating. A 300 HP there is only a .9 PSI drop! As well as being extremely efficient, these cores have a very high flow rate of 1030 CFM at 1.5 PSI, allowing it to handle as much boost as the engine is configured withstand. Further, the core is rated for 690 crank HP! All from an intercooler is designed to fit into the stock location!
