Shop electronics 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 sensors, gauges, wiring and monitoring electronics 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 electronic part in this collection is fitment-tagged for a WRX STI, but applications vary widely across the GD, GR/GV and VA generations and their different factory systems. Confirm your generation, year and trim on the product page before ordering.
Gauges and monitors let you watch things like boost, oil pressure and fluid temperatures that the factory cluster does not show in detail. On a modified car they are cheap insurance - catching a problem early is far cheaper than catching it late.
