Perusing through the 150+ datalogs we see another reason dyno's don't show everything. See the screencap below, can anyone guess which one has the CAI and which one doesn't?
(No, we don't make one for the BRZ so not a sales thing!)
Will it show gains on the dyno? Nope. Will it give you a bit more in the midrange on the street? Heck yes. Hats off to Perrin for the intake above. No tuning changes necessary so it is the same exact size, and we can see up top the airflow is peaking at 160 g/s vs 154 stock. (not pictured). Not a huge deal, but if you increase the rev limit it is important. Of note, it is not as simple as rigging some aluminum together....
