Second Hand BMW M8 Bonnet Strut

Yes, the BMW M8 uses gas-filled bonnet struts (also called bonnet lifters or bonnet supports) rather than a traditional prop rod, so they are a genuine part for this model. There are typically two struts, one on each side of the engine bay, holding the bonnet open when raised. If your strut has collapsed or is leaking, a used replacement from a breaker is a straightforward find.

The BMW M8 (F91/F92/F93) was introduced in 2019, and a significant facelift arrived for the 2022 model year, bringing changes to the front end including revised lights and bumper. Because bonnet struts are mounted to the bonnet and inner wing, the generation platform is the same across that boundary, but whether the strut mounting points and bonnet geometry carried over exactly through the facelift is something you should confirm with the breaker against your registration before buying.

For bonnet struts, the body style difference between the Coupe (F92), Gran Coupe (F93), and Convertible (F91) is very unlikely to matter, because the front end, bonnet, and strut mounting points are shared across the body styles within the F9x generation. You can treat any F9x M8 donor as a potential match regardless of whether it is a two-door, four-door, or convertible. Always confirm part numbers with the breaker against your registration to be certain.

Trim level does not affect bonnet strut fitment — the M8 and M8 Competition share the same bonnet and front-end structure, so the strut is the same part regardless of which variant the donor car is. The Competition badge denotes engine and chassis differences, not bodywork changes, so there is no fitment concern here. You may simply search for any F9x M8 donor strut without worrying about whether it came from a Competition or standard car.

Gas-charged bonnet struts do commonly weaken or leak over time, especially on cars that have been stored or used in cold climates, and it is one of the more frequent minor faults on used premium cars. A used strut from a breaker is a popular and cost-effective solution, provided the donor car is from the same generation and preferably the same facelift period as your vehicle. Ask the breaker to confirm the part against your registration number to ensure the correct strut length and mounting type.

A good breaker should be able to test the strut by compressing it fully and checking that it extends smoothly and holds resistance — a strut that collapses easily or extends with no resistance is already spent. Ask the breaker directly how the strut was removed and whether it was holding the bonnet up on the donor vehicle at the point of dismantling. Buying from a breaker who offers a short parts warranty gives you extra peace of mind on a part like this.
