Hoods' Heaters is a term used to describe the combination of GATS and RODS, two components of a car's exhaust system. GATS stands for 'Gasoline-Air-Turbine-System' and is responsible for controlling the air-fuel mixture in the engine. RODS stands for 'Rear-Oxygen-Duct-System' and is responsible for controlling the exhaust gases from the engine. Together, these two components help to keep the engine running efficiently and reduce emissions.
