Shop intake systems 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. You will find intake systems, air filters, inlet hoses and piping 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 intake systems fit my Subaru WRX STI across the GD, GR/GV and VA generations?
Every intake part in this collection is fitment-tagged for a WRX STI, but intake layouts vary across the GD, GR/GV and VA generations, so a system for one generation does not automatically suit another. Confirm your generation and year on the product page before ordering.
Will an intake require a tune?
Some intakes are designed to run safely on the stock calibration, while others change the airflow the ECU expects and require a tune. The product page will say which; when a tune is required, budget for it as part of the install.
