Show original supplier description
The Extreme Turbo Systems 04-07 Subaru STI Front Mount Intercooler Piping Kit is engineered for optimal airflow and durability. Constructed from 2.5" OD 304 stainless steel tubing, the pipes are one-piece mandrel bent, eliminating welds and joints that could impede flow. This design ensures maximum performance and reliability. This piping kit is finished with a wrinkle black powder coat for a sleek look and enhanced protection. The pipes feature beads on the ends to keep couplers firmly in place, even under high-performance driving conditions. It is compatible with various turbocharger outlet sizes including 1.75" (Stock Turbo), 2.00" (Aftermarket Turbo), and the ETS Rotated Turbo Kit. Users can also select their preferred Blow Off Valve flange, with options for Stock BOV, HKS BOV, TurboSmart BOV, and TiAL BOV. The kit is available for 2004-2005 and 2006-2007 model years. Important notes for installation: the ETS Rotated Turbo Kit option does not include the turbo kit pipe itself. Additionally, this kit does not work with fog lights. For a complete intercooler system, the intercooler unit can be purchased separately. One user reported an increase in HP from 447 to 506 after installation.
