Throttle Body Hose

Throttle body hoses connect the air intake system to the throttle body, facilitating airflow for combustion. These flexible, typically rubber or silicone, hoses maintain a sealed connection despite engine vibration and temperature fluctuations. Reinforced construction resists collapsing under vacuum, ensuring consistent airflow readings to the engine control unit. Variations include straight, curved, and flanged designs to accommodate diverse engine bay configurations. Proper sealing is critical to maintain accurate air/fuel mixture and prevent diagnostic trouble codes.
