How They Work:
-
Aerodynamics & Fuel Economy: When the vehicle is cruising at highway speeds and doesn't require maximum airflow for cooling, the computer closes the shutters to reduce wind drag and improve fuel efficiency.
-
Temperature Regulation: They automatically open when the engine, transmission, or intercooler needs extra cooling, and close during cold starts to help the engine reach its optimal operating temperature faster.
-
Why It Matters for Part Number BX1730:
The Blue Ox BX1730 baseplate is specifically engineered for select Chevrolet Equinox models (including the RS trim) that do not have lower shutters.
