It has been a while since we have updated this project, but we now have something for our WRX community!
The brief data report below shows our gains with this race intake project and our baseline was a fully stock 2015 WRX with no upgrade or aftermarket tune. The numbers are quite high due to the upgrades already installed on the WRX during testing. These upgrades included our Mishimoto:
- Downpipe
- Cat-Back Exhaust
- Front-Mount Intercooler
- Custom Engine tune

The graph above shows that the race intake coupled with the Mishimoto upgrades netted peak gains of about 77hp with 88ft-lb of torque, and max gains of about 86hp and 98ft-lb of torque against a fully stock WRX. Considering the vehicle's bolt-on additions and custom tune, we were expecting big gains. Of course, such large gains are possible only with the installed upgrades, but our intake and a proper tune contributed as well.
Regardless of any bolt-on upgrades, it is important to note that
