Subaru Top Mount Intercooler Black Ascent 2019-2022
California Residents: Prop 65 Warning
This part is legal for sale and use on Emissions Controlled Vehicles in all 50 states when used in accordance with the manufacturer's application guide because it has a California Air Resources Board (CARB) Executive Order (EO) number:
The COBB Top Mount Intercooler for the Subaru Ascent 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 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.
Upgrading the intercooler on your Subaru Ascent can help to both increase airflow and reduce charge air temperatures, leading to higher, more consistent power! Where a front-mounted intercooler may shine with overall cooling capacity, it comes at the price of transient response. The COBB Top Mount Intercooler is perfect for applications where additional airflow and cooling is desired without the desire to increase lag.
