We show basic details only for this EO. Its vehicle list is not a ruled table we can read reliably (often a scanned table or a list in the text), so we do not copy it. Check the vehicles and part numbers in the original PDF.
What the EO says about the part
The High Flow Air Flow Meter consists of a higher capacity air flow meter housing designed to use the vehicle's original sensing element and permit greater airflow into the engine. This Executive Order is valid provided that the installation instructions for the High Flow Air Flow Meter will not recommend tuning the vehicle to specifications different from those of the vehicle manufacturer.
