BMW F21 M135i 450 hp / 605 Nm

BMW F21 M135i 450 hp

The stock output of 326 hp already makes the M135i faster than average, but as we know, the BMW N55 engine has a lot more power in store. So we carried out a Stage 2 optimization and transformed the car into a wolf in sheep’s clothing. After our cure, the car achieved an output of 450 hp and 605 Nm.

Technical changes

To ensure that the performance of 450 hp is stable and legal and that the engine remains durable, we have made some changes: Replacement of the standard air filter with a sports air filter, installation of a 200-cell, divert-air valve, intercooler and upgrade spark plugs.


infinitas Software-Optimization

After the hardware changes, our engineers individually tuned the vehicle to RON 102 octane on our in-house dynamometer. In addition, a transmission software optimization was also carried out and the VMAX was raised to 300< Km/h.






Our Stage 2 conversion with 450 hp can be realized from approx. 7,500 €.


More power possible

infinitas stands for almost unlimited possibilities and the highest quality! That’s why 450 hp is not the end of the possibilities, because we can also offer performance above that for vehicles with the N55 engine.

Power in excess of 500 hp is also possible on request. There are also performance stages with the option of TÜV registration. < send Request >
