Purpose and technical function

The presented Bonnet Catch BMW G20 G21 F90 Upper Engine Hood Slam Top Latch Lock operates in the front body area, responsible for stable closing of the engine hood and cooperation with the latch mechanism and opening cables. A correctly selected component of this type is crucial for:

• safely keeping the hood in the closed position while driving,
• proper positioning of the hood relative to the fenders and the front panel,
• correct operation of the hood release lever from the cabin.

Thanks to the preservation of the original geometry and mounting points, the lock allows for installation without interfering with the front panel structure.

Benefits of using an original BMW hood lock

Using an original BMW hood lock in 3 Series G20/G21 and 5 Series F90 models allows you to maintain factory body panel fitment and predictable operation of the opening mechanism. Compared to replacements, the original component ensures:

• compliance with factory tolerances and body lines,
• properly selected stiffness and resistance to dynamic loads,
• compatibility with factory cables, catches, and hood guides.

This solution is particularly recommended for post-accident repairs, where it is essential to restore the original geometry of the vehicle's front and maintain the convenience of hood operation.

Condition, origin, and economic aspect

The offered hood lock is an original used BMW part, sourced from dismantling. This type of component allows you to combine repair cost control with the high quality of workmanship characteristic of factory-installed parts. Choosing a used BMW hood lock is beneficial both economically and ecologically – it reduces the consumption of new raw materials while maintaining an appropriate technical standard.

Professional installation and fitment

Due to its design, the lock is intended for installation in factory mounting points in the front part of the body. Installation by a workshop with experience in the BMW brand is recommended, which allows for:

• correctly setting the position of the lock relative to the hood catch,
• adjusting the height and pressure of the engine hood,
• checking the cooperation with the cable and the opening lever in the cabin.

Careful adjustment after installation minimizes the risk of play, difficult closing, or excessive resistance when opening the hood.
