Intercooler Assembly

The Subaru 21821AA030 is a genuine, direct-replacement intercooler complete assembly, specifically manufactured by Subaru to maintain the integrity and performance of your vehicle's charging system. Its primary function is to cool the compressed air from the turbocharger before it enters the engine, which increases air density and allows for more efficient combustion, thereby enhancing power output and engine performance. The assembly includes all necessary components for a complete installation. Installation involves disconnecting the battery, removing the engine cover, and carefully detaching air bypass hoses and the intercooler itself. It's recommended to replace the gasket when installing a new intercooler. Specific procedures for removal and installation vary slightly by model, such as the Subaru Impreza or Legacy, but generally follow a reverse order of the removal steps. This genuine Subaru Inter Cooler Complete assembly is compatible with a range of Subaru vehicles equipped with the 2.5L H4 Turbo engine, including the 2009-2012 Forester (XT, XT Limited), 2008-2011 Impreza (2.5 GT, WRX, WRX Sport, WRXSS), 2008-2012 Impreza STI (2.5 GT, WRX, WRX Sport, WRXSS), 2008-2012 Impreza WRX (2.5 GT, WRX, WRX Sport, WRXSS), and 2008-2009 Legacy (GT, GT Limited, XT Limited). It carries Subaru's factory warranty.
