Shop engine 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, and one engine family underpins the whole range: the turbocharged EJ flat-four, with the EJ257 2.5-litre for North American models from 2004 to 2021 and the EJ207 2.0-litre as the JDM-only counterpart. You will find internals, gaskets, engine mounts, pulleys, hardware 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 engine against the product fitment notes before ordering.
What engine parts fit my Subaru WRX STI across the GD, GR/GV and VA generations?
Every engine part in this collection is fitment-tagged for a WRX STI, but confirm which EJ application it is for: North American cars from 2004 to 2021 use the EJ257 2.5-litre, while the EJ207 2.0-litre is the JDM-only counterpart. Confirm your generation, year and engine on the product page before ordering.
Do all STIs in this range share the same engine?
They share one engine family, not one identical engine: the turbocharged EJ flat-four underpins the whole aggregate range, as the EJ257 2.5-litre in North America from 2004 to 2021, with the EJ207 as the JDM-only counterpart. Shop by your car's exact EJ application and generation, not just by the STI name.
