What the EO says about the part

The High Flow Throttle Body includes a modified throttle body with a larger diameter for increased air flow. No other modifications are required for installation other than the replacement of the stock unit with Dinan's unit. This Executive Order is valid provided that the installation instructions for the High Flow Throttle Bodies will not recommend tuning the vehicle to specifications different from those of Dinan Engineering.

Quoted from EO D-176-41. The EO exempts the part from California Vehicle Code Section 27156 only for the vehicles it lists.
