Cobb 04-07 Subaru WRX / STI Front Mount Intercooler Hot Pipes
These Cobb Front Mount Intercooler Hot Pipes replace the restrictive factory pipes on 2004-2007 Subaru Impreza WRX and STI models equipped with a front mount intercooler. Mandrel-bent from 6061 aluminum tubing with a 2.5-inch diameter, they deliver smoother airflow from the turbocharger to the intercooler core. Expect sharper throttle response, quicker turbo spool, and consistent power gains across the RPM range.
Key Features
- Mandrel-Bent 2.5″ Aluminum Tubing: Provides larger diameter than stock 2″ pipes for unrestricted airflow and reduced restrictions.
- Black Wrinkle Powder Coat Finish: Resists corrosion, withstands high underhood temperatures, and maintains a clean appearance.
- Direct Bolt-On Design: Matches factory routing and mounting points for simple installation on FMIC-equipped WRX/STI models.
- Improved Turbo Efficiency: Minimizes heat soak and pressure drop to support higher boost levels and reliable performance.
- Complete Kit: Includes all necessary silicone couplers, T-bolt clamps, and hardware for a secure fit.

Installation Notes
- Professional installation recommended.
