Shop cooling 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 top-mount intercooler layout is common to the 2008-2021 STI range. You will find radiators, fans, hoses, thermostats and oil coolers 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.
Every cooling part in this collection is fitment-tagged for a WRX STI, but applications vary across the GD, GR/GV and VA generations. The top-mount intercooler layout is shared across the 2008-2021 range, while other cooling parts are more generation-specific — confirm your generation and year on the product page before ordering.
Top-mount intercoolers come closest: the top-mount layout is common to the 2008-2021 STI range, and a direct-fit top-mount intercooler is listed as a single application for 2008-2021 WRX STI, making TMIC upgrades one of the few genuinely cross-generation cooling categories. Still confirm your exact year in the fitment notes.
