What the EO says about the part
The Bronco ROUSH Air Induction System consists of a new air box lid with see-thru window and an air filter to replace the stock components. The stock airbox and hydrocarbon trap (HCT) are retained and not modified in any way. The stock inlet snorkel is reconnected to the new lid. No sensors are modified or relocated, and the electronic control unit (ECU) is not re-flashed as part of this installation. Installation of the Bronco ROUSH Air Induction System requires the removal of the stock air filter lid.
Quoted from EO D-418-49. The EO exempts the part from California Vehicle Code Section 27156 only for the vehicles it lists.
