The new BMW 340i is just about to hit the market, yet BMW is already working on an M Performance Power Kit. Along with a facelift, the F30 3 Series family changes its 335i model for the 340i powered by a new 3.0 liter inline-six cylinder (B58) producing 326 horsepower and 450 Nm (332 lb-ft) of torque.

The previous power kit offered for the 335i had an output of 320 horsepower and the same 332 lb-ft of torque.

If we apply the same formula, then we expect the M Power Kit to offer anywhere from 20 to 30 horsepower extra and torque of 370 lb-ft.


Developed through consultation by the engineers at BMW M, the M Performance Power Kit is usually available through all Authorized BMW Centers in the US. The previous M Power Kit for the top of the line 3 Series had an MSRP starting at $1,100 (plus Installation) and retained BMW’s 4-Year / 50,000-mile New Vehicle Warranty.

If the previous kit development is an indication, then the 340i and consequently the 440i, will receive a re-mapped accelerator pedal calibration for more dynamic throttle response, along with an “exhaust burble” sound during engine overrun conditions.
The kit also includes updated software or replacement engine DME (electronic control unit), high-capacity engine air intake system, signature BMW M Performance engine cover, and rocker panel decals.

No launch date has been announced at the moment.
