What cooling parts fit my Subaru WRX STI 2015-2021 (VA chassis)?
Every cooling part in this collection is fitment-tagged for the VA-chassis WRX STI (2015-2021) with the EJ257 engine. The top-mount intercooler layout carries through the whole VA run, but confirm your year and exact configuration on the product page before ordering.
Why does intercooler cooling matter on the VA STI?
The VA STI keeps the top-mount intercooler layout, so keeping charge temperatures down is part of consistent performance. Subaru made the point on the S209, which revived an intercooler water spray system — a nod to the 2004-07 WRX STI — specifically to lower intercooler temperature.
