( Brand: Vortec ), ( Manufacturer Part Number: 7035ES )
The Vortec 7035ES ITW (Intake Manifold with Throttle Body) is a crucial component of General Motors' small-block V8 engines. This intake manifold and throttle body assembly is designed to optimize the airflow and fuel delivery to the engine for improved performance and efficient combustion.
The Vortec 7035ES ITW is a multi-port design, featuring a series of runners that distribute the air and fuel mixture evenly to each cylinder. The intake manifold is made of aluminum for reduced weight and enhanced heat dissipation. It is also designed with a wet-flow runner design, which improves fuel atomization and ensures a more complete combustion process.
The throttle body integrated into this assembly is responsible for controlling the flow of air into the engine based on the driver's input through the accelerator pedal. It features a 60-pound-per-hour (lb/h) mass airflow sensor, which measures the amount of air entering the engine to calculate fuel delivery. This helps maintain optimal air-fuel ratio for efficient combustion and reduced emissions.
The Vortec 7035ES ITW is also equipped with a secondary air system, which injects heated air into the exhaust ports during cold start-up to help the engine reach operating temperature more quickly. This system contributes to improved cold-start performance and reduced emissions.
The intake manifold and throttle body are designed to work seamlessly together, providing precise and responsive engine performance. The Vortec 7035ES ITW is a high-quality, factory-engineered component that meets or exceeds original equipment manufacturing (OEM) specifications for fit, function, and durability. It is an excellent choice for those seeking to maintain or restore the performance of their V8 engine.
