Purpose and technical function

The Bonnet Catch BMW G20 G21 F90 Upper Engine Hood Slam Top Latch Lock acts as the final element of the engine hood locking system, working in conjunction with the hood striker and the cabin release mechanism. It is responsible for:

• securely locking the hood once closed,
• maintaining constant pressure of the hood against the front panel,
• stabilizing the hood at higher driving speeds,
• proper release of the lock during opening.

Thanks to its factory geometry and fitment to the BMW design, this component allows for maintaining the correct alignment of the hood relative to the fenders and bumper, which is important for both safety and body aesthetics.

Construction and fitment for BMW

The offered lock belongs to the Hinges, locks and other hood parts group, meaning it has been designed specifically for operation in the front engine compartment zone. The construction provides:

• factory mounting points for front reinforcements,
• a properly shaped locking part that works with the hood striker,
• a release mechanism adapted to the standard opening cable.

Its original BMW origin helps maintain the proper rigidity of the connection, reduces the risk of play, and facilitates installation without the need for structural modifications.

Condition, verification and benefits of installation

The item is offered in used condition, which in practice means a favorable combination of price and the preservation of the manufacturer's original specifications. This type of component is particularly useful for:

• repairs after a collision in the front part of the body,
• resolving issues with the hood not closing properly or lifting on its own,
• restoring the factory fitment of the engine hood.

Choosing a genuine BMW bonnet lock reduces the risk of adjustment problems and minimizes the need for additional work when fitting the part to the existing vehicle structure.

How to choose the right bonnet lock

When selecting this type of part, it is crucial to verify compatibility with the specific BMW model and compare the lock's design with the element currently installed in the car. It is worth paying attention to:

• the arrangement of mounting holes,
• the shape of the locking part,
• the method of attaching the opening cable.

Additionally, it is helpful to use the OEM number and interchangeable numbers, which allow for precisely confirming compatibility with a specific body version and model year.
