Genuine BMW E9 Hood Cowl Corner Rubber Seal – NOS – 51711810529

Genuine BMW New Old Stock rubber seal for the hood and cowl area of classic BMW E9 Coupé models.

This short profiled rubber seal is installed in one of the outer corners beneath the rear section of the hood, directly below the windshield and cowl ventilation area. It helps prevent water, dirt and debris from entering the cavity beneath the cowl.

The same seal is used on both the left- and right-hand side. Two seals are normally required per vehicle.

This listing is for one seal only. The stated price is per piece.

• BMW 3.0 CS
• BMW 3.0 CSi

• Manual- and automatic-transmission versions where applicable

Compatibility may depend on the vehicle’s production date, market specification and previous bodywork or restoration work.

Always compare the BMW part number, rubber profile, length and mounting position with the original component before ordering.

Installation position

One seal is installed on each side of the vehicle in the outer corners beneath the rear section of the hood, close to the windshield and cowl ventilation openings.

The seals fit into the corresponding body channels and help prevent water and contamination from entering the cavities beneath the cowl area.

Because these seals are often removed during body restoration or repainting, they are frequently missing from otherwise complete BMW E9 vehicles.

Condition

Genuine BMW New Old Stock item that has never been installed.

The original BMW packaging and identification labels show substantial age- and storage-related wear, including:

• Torn and deteriorated original packaging
• Discolouration and dirt on the original labels
• Storage dust and cosmetic marks
• Possible light storage deformation of the rubber
• General ageing consistent with a decades-old original BMW rubber component

Because this is an older NOS rubber part, its flexibility and condition must be checked before installation.

Supplied exactly as shown in the photographs.

Included

• One genuine BMW profiled rubber seal
• Original aged BMW packaging and identification labels shown in the photographs

Only one seal is included. A second seal is required to complete both sides of the vehicle.

No adhesive, body trim, cowl components, mounting tools or additional seals are included.

Important quantity information

This listing is for one rubber seal.

The same BMW part number is used on both sides of the vehicle. BMW specifies a total quantity of two seals per car.

The stated price is per piece.

Installation recommendation

Before installation:

• Confirm the BMW part number and rubber profile
• Check the NOS rubber for cracks, hardening or deterioration
• Carefully clean the body channel and surrounding cowl area
• Remove old adhesive, dirt and corrosion where necessary
• Compare the mounting position with the opposite side
• Install the seal without excessively stretching or folding the rubber
• Confirm that the hood closes correctly after installation
• Check that the seal does not obstruct the intended water drainage paths

Installation should preferably be carried out by someone familiar with BMW E9 body seals and cowl construction.
