Cobb 2015-2021 Subaru WRX Top Mount Intercooler – Silver (Requires COBB Charge Pipe)
The COBB Top Mount Intercooler serves as a direct replacement for the factory unit on 2015-2021 Subaru WRX models. Its oversized bar-and-plate core delivers increased cooling capacity to maintain lower intake air temperatures during extended runs. This upgrade supports higher boost levels while fitting under the stock hood with no modifications.
Key Features
- Bar-and-Plate Core: 21.5″ x 12.25″ x 3.0″ dimensions provide 546% more volume than stock for rapid heat rejection and stable IATs.
- End Tanks: Cast 6061-T6 aluminum construction handles high pressures and resists cracking under boost.
- Direct Fit Design: Bolts into factory locations using OEM shroud and ducting for simple swap.
- Silver Powder Coat: Durable finish protects against corrosion and heat while matching engine bay components.
- USA Made: Built with precision welding and quality materials for long-term durability.
Product Notes
- Requires COBB SF Charge Pipe Kit (part 47505B or similar) due to larger core thickness.
- Retains all factory air routing and sensors for plug-and-play operation.
- Ships ready-to-install with included hardware; weight 19 lbs.
Installation Notes
- Professional installation recommended.
- Remove OEM intercooler and charge pipe; install COBB charge pipe first.
- Use provided gaskets; torque fittings to 20-25 ft-lbs per COBB guidelines.
