Mercedes M104 Keychain

The Mercedes M104 is a straight-six that remains one of the brand’s most beloved engines. Introduced in the early 1990s as the successor to the M103, it powered models like the 300E-24 (W124), E 280 / E 320 (W124/W210), C 280 (W202), and even the SL (R129). With a 24-valve cylinder head, electronic fuel injection, and outputs ranging from 193 to 231 hp, it is regarded as the last classic inline-six before Mercedes moved on to the M112/M113 V-engines. Our keychain miniaturizes its distinctive head-gasket outline—subtle at first glance, but instantly recognizable to Mercedes enthusiasts.

Built with a cast-iron block and alloy head, featuring twin overhead cams, the M104 came in 2.8- and 3.2-liter versions known for smooth revving and refined manners. In the 24V W124s it put an end to the “only” 12-valve era and moved Mercedes into a new performance class. Common enthusiast discussions include head-gasket wear (a well-known topic at higher mileage), ignition coils, mass airflow sensors, and the reliability of KE-Jetronic vs. later injection systems.

For many enthusiasts, the M104 strikes the perfect balance: refined enough for long-distance touring, strong enough for spirited driving, and robust enough to exceed 400,000 km with ease. In the tuning world it also has a following, with tubular headers, free-flow exhausts, or even turbo conversions unleashing impressive performance. The 3.2-liter version is particularly popular as a swap into lighter chassis, turning them into true sleepers.

This keychain is not just an accessory—it’s a collectible piece of Mercedes heritage. A thoughtful gift for W124, W202, or R129 owners, and equally something to keep for yourself if you love the M104. At first glance refined, at second glance a true insider detail, guaranteed to spark conversations at classic meets, fuel stops, or in the workshop.

Proudly crafted in Germany, meticulously detailed and finely finished for a refined in-hand feel paired with a premium brushed surface.
