The F-connector is located on the air intake boot and provides a connection point for the vacuum lines that run to the brake booster and fuel pressure regulator. The factory connector is made of plastic and with heat and exposure to the elements the connector becomes brittle and potentially cracks. As a result, a vacuum leak occurs which can cause poor idling issues, evap fault codes, and poor performance.
This aluminum version from ECS Tuning is impervious to these issues, and will easy outlast the rest of your plastic and rubber vacuum system components.
This item fits the following BMWs:
E39 525i 530i
E46 325i 325xi 330i 330xi
Z3 2.5i 3.0i

Easily cleaned with warm, soapy water—no oiling required
