Genuine OEM Volkswagen Injection Throttle Seal, part number 07K129748A. This seal is designed to create a tight, leak-proof connection for the injection throttle component, preventing unwanted air ingress or egress that could affect engine performance. It is positioned between mating surfaces of the throttle body or related injection components. Made from a durable, flexible material, likely rubber or silicone, and weighing only 0.008 kg, it maintains its sealing properties under engine heat and pressure. Using a genuine OEM seal ensures the correct material composition and precise dimensions for a perfect fit, critical for maintaining proper air-fuel mixture and engine efficiency.
