Description
Mishimoto developed this oil catch can kit for the 2015-2021 Subaru WRX as a focused upgrade that helps reduce the amount of oil vapor recirculated through the intake tract.
How it supports the build
Because the 2015-2021 Subaru WRX is commonly used as a performance platform that can generate substantial heat under repeated load, for modified or direct-injected platforms, managing oil vapor can be a sensible part of a broader reliability-focused build. The benefit becomes clearer during tuned street builds, canyon driving, autocross, roll-on acceleration, and track days.
Because this listing is specific to the 2015-2021 Subaru WRX, it should be evaluated alongside the vehicle’s current cooling, airflow, power, tire, and track-use setup as applicable.
Recommended driver
Best match: enthusiasts who track, autocross, or drive at sustained RPM. The upgrade is most worthwhile for a car that is driven often enough and hard enough for the factory component to become part of the build plan.
