Genuine BMW E21 Center/Left Fresh-Air Vent Grille – 64221366638 NOS

New-old-stock genuine BMW fresh-air ventilation grille for the dashboard of facelift BMW E21 models produced from approximately 08/1979 onwards.

This grille forms part of the original dashboard ventilation system and directs fresh air from the heater and ventilation ducts into the passenger compartment.

BMW used the same component in selected centre positions and for the left-hand dashboard outlet. The required position and quantity depend on the vehicle’s ventilation configuration.

The full BMW catalogue number is 64221366638. The shortened number marked or referenced on the component is 1366638.

This original BMW interior component is no longer manufactured and has become difficult to find in unused condition.

This grille can be used in selected centre positions and in the left-hand dashboard position. The BMW catalogue lists multiple units for some ventilation layouts.

It is generally not suitable for pre-facelift E21 models produced before approximately 08/1979, as these vehicles use a different fresh-air grille arrangement.

Condition

This is a genuine BMW new-old-stock component that has never been installed.

Due to its age and extended storage, the component may display minor cosmetic characteristics, including:

• Light dust or storage marks
• Minor surface discolouration
• Small marks from contact with packaging
• Normal ageing of the black plastic
• Minor imperfections on concealed mounting surfaces

The grille should be inspected before installation, particularly around the mounting tabs, pivots and louvres. Original plastic components can become more fragile after decades of storage.

Included

• One genuine BMW fresh-air ventilation grille
• Supplied as one individual component

The listing is for one grille only. Check how many pieces are required for the intended installation position before ordering.

No dashboard panel, air duct, heater housing, right-hand grille, mounting clips or other ventilation components are included.

Installation recommendation

Before installation:

• Compare the part number and shape with the original grille
• Confirm whether it is required for a centre or left-hand position
• Inspect all mounting tabs and pivots
• Clean the dashboard opening and ventilation duct
• Remove the old grille carefully
• Align the replacement component before applying pressure
• Do not force the grille into the dashboard opening
• Check that the louvres move correctly after installation

Installation should preferably be carried out by someone familiar with BMW E21 dashboard and ventilation components, as the surrounding original plastic may be brittle.
