ID1050x Top Feed Fuel Injectors Set of 4

• 2008–2021 Subaru | WRX STI
• 2002–2014 Subaru | WRX

The ID1050x is the evolution of the ID1000 in Injector Dynamics' X-Series, developed with Bosch Motorsport as a purpose-built motorsport injector rather than a modified production part. This set is matched for the EJ-powered WRX and WRX STI, with the fitment-specific adapters the Subaru top-feed rails need.
