Shop turbo parts for the Subaru WRX STI across the GD, GR/GV and VA generations. This aggregate covers the Impreza-based WRX STI through 2014 and the standalone WRX STI of 2015-2021, all built around the EJ-series turbocharged flat-four — the EJ257 2.5-litre in North American models from 2004 to 2021 — and the turbo model itself is generation-specific. You will find turbochargers, intercoolers, blow-off valves and boost control here — every part in this collection is fitment-tagged for the Subaru WRX STI across the GD, GR/GV and VA generations, so check your generation and year against the product fitment notes before ordering.
What turbo parts fit my Subaru WRX STI across the GD, GR/GV and VA generations?
Every turbo part in this collection is fitment-tagged for a WRX STI, but the turbo model is generation-specific across the GD, GR/GV and VA range, and special editions differ again. Confirm your generation, year and edition on the product page before ordering.
Is the factory turbo the same across STI generations?
No. The turbo model is generation-specific: the VF48 single-scroll unit is on US GR/GV cars, VA cars use carried-over EJ257 hardware, and the HKS-built unit is exclusive to the S209. Shop for your generation's turbo application, not a generic STI one.
