If you're a proud owner of a 2015-2021 Subaru WRX, the COBB Top Mount Intercooler (Part Number: B42405-BK) is a must-have upgrade for enhancing your vehicle's performance. Designed specifically for the DIT WRX, this intercooler not only boosts airflow but also improves cooling efficiency compared to stock and other aftermarket options.
With a substantial 31% increase in airflow over the stock intercooler, the COBB Top Mount Intercooler is engineered to deliver optimal performance. It features the largest core available for your WRX, measuring 15.75" x 9.65" x 3.94", ensuring that your engine stays cool even during demanding driving conditions. This intercooler is especially beneficial for those who want increased power without the need for an oversized turbocharger.
The COBB intercooler is built with cast aluminum end tanks that effectively direct charge air through a premium Garrett core. This design not only maximizes cooling but also simplifies the installation process compared to other popular intercoolers on the market. A heavy-duty replacement mounting bracket on the passenger side supports the added weight, while an included bushing helps isolate vibrations from the engine block.
Installation is further streamlined with reinforced black silicone couplers that enhance the flow path from the turbocharger to the throttle body. To top it off, the included COBB Thrust Tunnel, made from wrinkle black powder-coated aluminum, connects to the factory hood ducting to further optimize airflow through the core.
To complete the installation, a COBB Charge Pipe Kit is required. You can find the full kit here.
Upgrading your WRX's intercooler can significantly reduce charge air temperatures and increase airflow, leading to a noticeable boost in power. While front-mounted intercoolers may offer superior cooling capacity, they often compromise transient response. The COBB Top Mount Intercooler strikes the perfect balance, making it an ideal choice for performance enthusiasts looking to enhance their driving experience.
One 2018 WRX owner shared, “After installing the COBB intercooler, I noticed a huge difference in throttle response and power delivery. The installation was straightforward, and the fitment was perfect. I can definitely feel the extra airflow during spirited drives.”
