Our first segment of this STI intercooler project involved the test fitting of our WRX crash beam and intercooler core. We were able to verify fitment of both pieces, which allowed our team to move on to piping fabrication. We are starting this kit with the cold-side pipe, which we've decided to place this on the passenger side of the engine bay to reduce the piping length as much as possible. Following this strategy should help reduce lag seen by the driver.
Pipe Fabrication
The cold-side pipe is a great place to start because we are able to use a portion of one of our existing kits. Because the 2015 model shares the EJ from the 2008+, we will be reusing the pipe that attaches to the throttle body and incorporates the BPV (bypass valve).
