Fitment: 2015 - 2021 Subaru WRX. Upgrading the intercooler on your 2015 and newer WRX is a great way to boost airflow and lower charge air temperatures, which directly translates to more power. While front - mounted intercoolers offer high cooling capacity, they sacrifice transient response. The COBB Top Mount Intercooler is ideal when you want extra airflow and cooling without a large upgraded turbocharger. Key features include a Thrust Tunnel that maximizes airflow from the hood duct, a 31% increase in airflow compared to the stock intercooler, and a black powder - coated finish core. It has cast aluminum end tanks, is compatible with the stock or COBB LF BPV, and measures 15.75' x 9.76' x 3.94'. It retains clearance for aftermarket radiators. Installation requires the COBB Charge Pipe Kit and is of intermediate difficulty. An installation guide is provided. This intercooler for the 2015 - 2018 Subaru WRX offers a major boost in overall airflow and more efficient cooling than other top - mount options. A heavy - duty replacement mounting bracket on the passenger side handles the extra weight of the COBB intercooler core, and an included bushing isolates engine vibrations. Reinforced black silicone couplers complete the installation, maximizing the flow path from the turbocharger to the throttle body. The COBB Thrust Tunnel, made of wrinkle black powder - coated aluminum, attaches to the factory hood ducting to optimize airflow through the core.
Using the COBB Top Mount Intercooler is straightforward. First, make sure you have the COBB Charge Pipe Kit as installation requires it. Follow the included installation guide step - by - step. It's an intermediate - level installation, so if you're not experienced, you might want to seek professional help. Once installed, your Subaru WRX will benefit from increased airflow and lower charge air temperatures. As for maintenance, regularly check the reinforced black silicone couplers for any signs of wear or damage. Also, keep an eye on the mounting bracket and the bushing that isolates engine vibrations. If you notice any issues with the airflow or cooling performance, it could be a sign that something needs attention. Clean the intercooler periodically to ensure maximum efficiency. Just use a mild cleaner and a soft brush to gently remove any dirt or debris. And that's all you need to know to get the most out of your COBB Top Mount Intercooler.
