COBB Tuning Silver Front-Mount Intercooler Kit for VB Subaru WRX [746550-SL]

COBB Tuning Silver Front-Mount Intercooler Kit for VB Subaru WRX [746550-SL]

The COBB Front Mount Intercooler Kit for the Subaru WRX delivers a significant improvement in airflow and cooling efficiency compared to top-mounted intercoolers. Featuring a vertical flow Garrett core measuring 24″ x 8″ x 3.5″, this design optimizes vehicle packaging and pipe routing. The end tanks, made from formed sheet aluminum and tapered for even pressure distribution, maximize cooling performance. The intercooler itself is finished in silver powder coat, while the rest of the kit is coated in black for a sleek contrast.

Thrust Tunnels

• COBB Tuning integrates “Thrust Tunnels” on both ends of the intercooler core to provide structural support and enhance airflow. These tunnels direct air through the intercooler and the rest of the vehicle’s cooling stack. The passenger-side tunnel includes mounting points for the Ambient Temperature Sensor. Both tunnels are finished with wrinkle black powder coat for durability and a refined look.

Included Support Beam

• The kit includes a bumper support beam, as the factory crash bar must be removed for installation. Constructed from 1/8″ steel plating and 1.5″ DOM tubing, the support beam is finished in matte black powder coat and features an integrated tow hook mount on the passenger side in the factory location.

Mandrel Bent Tubing

• The intercooler piping, engineered by COBB Tuning, is made from mandrel-bent 2″ and 2.5″ tubing with a wrinkle black powder-coated finish. The “hot” side incorporates a machined clip for seamless integration with the factory-style turbocharger outlet, transitioning from 2″ to 2.5″ before reaching the core inlet. The outlet pipe remains 2.5″ through to the custom billet throttle body adapter. All piping is compactly routed behind the passenger-side bumper cover, minimizing the flow path from turbocharger to throttle body.

Why?

• COBB Tuning’s Front Mount Intercooler for the 2022-2024 Subaru WRX enhances airflow and reduces charge air temperatures, ensuring more consistent and higher power delivery. Its innovative design achieves outstanding cooling efficiency without compromising transient response, avoiding the long piping associated with other FMIC systems.
