The COBB Tuning B41450-SL Top Mount Intercooler Kit (Silver) is a precision-engineered performance upgrade designed specifically for 2022–2025 Subaru WRX VB platform equipped with the 2.4L FA24 turbocharged engine. This intercooler represents the ideal balance of cooling efficiency, throttle response, and long-term reliability, making it equally well-suited for daily driving, spirited canyon runs, and sustained performance use.
The factory top-mount intercooler is a known bottleneck once intake air temperatures begin to climb. Under repeated acceleration or warm ambient conditions, the OEM core is prone to heat soak, leading to inconsistent power delivery and reduced engine efficiency. The COBB Top Mount Intercooler addresses these issues with a significantly larger, higher-flow Garrett bar-and-plate core paired with bespoke cast aluminum end tanks engineered for smooth, unrestricted airflow.
This intercooler kit installs directly in the factory location and retains OEM-style connections at both the throttle body and charge pipe, ensuring excellent sealing and factory-like drivability. COBB includes a wrinkle black powder-coated aluminum thrust tunnel designed to channel airflow from the hood scoop directly through the intercooler core, maximizing cooling efficiency even at low vehicle speeds. This kit is emissions compliant and carries multiple CARB Executive Orders, making it legal for use in all 50 states when installed as intended.
Finished in a clean silver coating, this intercooler not only delivers measurable performance benefits but also adds a premium, motorsport-inspired appearance to the engine bay.
While a top mount intercooler does not directly add horsepower on its own, the COBB Top Mount Intercooler dramatically improves the conditions required to maintain consistent power output. By reducing intake air temperatures and improving airflow efficiency, the engine can sustain optimal ignition timing and boost levels for longer periods.
Real-world benefits commonly reported with this intercooler include:
This intercooler also provides the thermal headroom needed to safely support future performance upgrades such as intakes, exhaust systems, and higher-stage ECU calibrations.
A top mount intercooler cools compressed air from the turbocharger before it enters the engine. Cooler air is denser, allowing for more efficient combustion and improved engine performance. Upgrading reduces heat soak and improves consistency under load.
Yes, we highly recommend ordering a custom tune to take full advantage of this intercooler kit.
Yes. The COBB B41450-SL carries multiple CARB Executive Orders and is emissions compliant when installed according to manufacturer guidelines.
Absolutely. The larger Garrett core and optimized airflow design significantly reduce heat soak compared to the factory intercooler, especially during repeated acceleration or warm weather driving.
