Vaico V20-1610 Fuel Injection Throttle Body Heater Hose - Inlet

Fuel Injection Throttle Body Heater Hose

The Vaico V20-1610 fuel injection throttle body heater hose routes coolant from the throttle unit to the cylinder head to support proper thermal management in the intake system. It is a direct-fit replacement for select BMW applications and is built to match the listed dimensions for the OE-style routing path.
