The Subaru OEM IHI VF48 Turbocharger is the factory turbocharger that came equipped in the Subaru WRX STI from 2008-2019 models and makes for a nice upgrade over the factory turbocharger.
NOTE: Subaru highly recommends purchasing a new Banjo Bolt and Screen (SUB 14445AA090) with any purchase of a new OEM turbo.
