Description:
This Kit includes both the Top Mount Intercooler in Black and the COBB Charge Pipe Kit.
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.
Cast aluminum end tanks direct charge air through a high quality Garrett core for unmatched cooling. This intercooler not only features the largest core available for the DIT WRX (15.75" x 9.65" x 3.94"), but remains easier to install than other popular options.
To handle the added weight of the COBB intercooler core, a heavy-duty replacement mounting bracket is used on the passenger side. An included bushing isolates vibrations from the engine block.
Reinforced black silicone couplers are included to complete the installation, maximizing the flow path from turbocharger to throttle body.
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.
The COBB Charge Pipe for the 2015-2021 Subaru WRX is constructed of 6061 aluminum tubing. An integrated billet transition smoothly takes diameter from 2" to 2.5" to allow for increased flow while maintaining clearance for larger aftermarket radiators. A wrinkle black powder coat finish gives an upgraded yet subtle appearance under the hood. The included billet turbo adapter and 5-ply silicone make for a straight forward and leak free installation and are compatible with both the factory bypass valve and COBB LF BPV.
