Please feel free to ask questions about the intake rather than resort to speculation. The intake offers the gains described by the dyno chart with no CEL and no changes to ECU. There are no programming changes necessary for the intake upgrade. The reason for this is the Yaris motor features a mass air meter which compensates for the additional airflow produced by the resonance tuning. The mass ai rmeter will address the extra airflow and offer the necessary extra fuel flow. The intake upgrade produced the same air/fuel curve as the stock manifold. These gains are not dependant on the CAI, but the combination of the CAI and intake will offer slightly more power than the intake and stock air box.

Will an aftermarket air filter be necessary, or can you just bolt the stock airbox back in?
Lots of questions but that's because I'm interested in the product. 10whp is too good a gain to turn down if it is plug and play.
