The ETS Evo Upper Intercooler Pipe is designed to eliminate many of the unnecessary bends in the stock piping that snake around the stock engine bay. Once the air passes through the intercooler, our upper intercooler pipe takes a short direct path around the core support, over the transmission and straight up to the throttle body. This unique routing is over two feet shorter than the stock routing which results in greatly improved spool up. With an 11% increase in cross sectional area, flow is increased as well. The short route configuration piping will require a small battery kit, or the battery must be relocated. The stock battery piping will allow you to use the stock battery.
