The COBB Top Mount Intercooler for the Subaru WRX offers a significant increase in overall airflow as well as more efficient cooling than other top mount intercoolers currently available. Bespoke cast aluminum end tanks direct charge air through a high quality Garrett core for unmatched cooling. Reinforced silver silicone couplers are included to complete the installation, maximizing the flow path from turbocharger to throttle body. The inlet side uses the stock charge pipe and o-ring seal. The outlet side uses the stock o-ring which seals over the throttle body inlet. The included COBB Thrust Tunnel is constructed of wrinkle black powder coated aluminum and attaches to the factory hood ducting to maximize airflow through the core. Tuning changes are not required to support this intercooler, it can safely be run on either stock Subaru calibration or COBB Stage 1 Off The Shelf (OTS) maps.   Features:

• 30% Airflow Increase Over Stock Intercooler
• Thrust Tunnel Maximizes Airflow from Hood Duct
• Compatible with Stock or COBB Stage 1 Tunes
• 20" x 7" x 4" Core
• Direct Replacement of OEM Intercooler
