Extreme Turbo Systems Front Mount Intercooler Piping Kit 04-05 Subaru STI - Wrinkle Black | 2.5" Stainless Steel | Intercooler Piping Kit

Overview

The Extreme Turbo Systems Front Mount Intercooler Piping Kit for the 2004-2005 Subaru WRX STI is designed to replace the factory intercooler piping with a durable, high-flow solution. This kit is ideal for STI owners looking to improve boost response and reduce pressure drop in their turbo system. By upgrading to mandrel-bent stainless steel piping, this kit supports higher power levels and enhances the overall efficiency of the front mount intercooler setup.

ETS engineers this piping kit with a focus on precision fitment and flow optimization. Using 2.5-inch outer diameter 304 stainless steel tubing, the pipes are formed in one-piece mandrel bends without welds or joints that could disrupt airflow. The wrinkle black powder coat finish not only provides corrosion resistance but also adds a subtle, OEM+ aesthetic that complements the engine bay. The inclusion of stainless steel T-bolt clamps and ETS black silicone couplers ensures a secure, leak-free connection under high boost conditions.

For Subaru WRX STI enthusiasts, this piping kit offers a reliable upgrade that supports tuning and power enhancements. The bead-rolled pipe ends prevent coupler slippage during hard acceleration, while the precise fitment reduces installation time and hassle. Although designed specifically for the 04-05 STI, this kit is a solid foundation for any front mount intercooler upgrade, contributing to improved throttle response and consistent boost delivery on both street and track applications.
