Second Hand BMW M4 Bonnet Strut

Yes, the BMW M4 does use gas-filled bonnet struts (also called bonnet lifters or bonnet shocks) to support the bonnet in the open position — you'll typically find one on each side towards the rear of the bonnet. These replace the older-style manual prop rod found on some vehicles, so if your strut has failed the bonnet will no longer stay up on its own. When buying used, make sure the replacement strut still has good gas pressure, as worn struts are a common reason for needing a replacement in the first place.

The BMW M4 has been produced in two main generations: the F82 (2014–2020) and the G82 (2021–present), with the F82 also receiving a Competition variant but no significant front-end facelift that would alter bonnet strut fitment during its run. Generation is the most important factor when sourcing a bonnet strut, as the bonnet itself differs completely between F82 and G82. Always confirm the generation matches your car before purchasing from a breaker.

Both 2016 and 2019 M4s fall within the F82 generation (2014–2020), and as there was no significant front-end facelift during this generation that would have changed the bonnet or its strut mounts, a strut from either year is generally expected to be compatible. That said, it is always worth confirming with the breaker against your specific registration, as minor production changes can occasionally affect parts. The F82 generation ran consistently enough that most breakers will treat these as a straightforward match.

Trim level does not affect bonnet strut fitment on the F82 BMW M4 — the bonnet and its supporting struts are shared across standard M4, M4 Competition, and M4 CS variants within the same generation. You may find cosmetic differences such as the colour of the engine bay or minor badging, but the strut itself is the same part. Confirm the generation (F82 or G82) matches your car and you can disregard trim level when speaking to a breaker.

No, the F82 (2014–2020) and G82 (2021–present) are completely different generations with different bonnets, so the bonnet struts will not interchange between them. When contacting breakers on Findapart, make sure you specify G82 or give your registration so they can confirm the correct generation. Fitting the wrong generation strut is very unlikely to work due to differences in both mounting points and bonnet geometry.

Engine choice does not affect bonnet strut fitment — the struts are mounted to the bonnet and inner wing, not the engine, so a strut from any engine variant within the same generation will be suitable. The key details to confirm with the breaker are generation (F82 or G82) and that the strut is in good working condition with adequate gas pressure remaining. Trim and engine specs are irrelevant for this particular part.
