The Porsche 911 991 series, produced between 2012 and 2016, is a legendary sports car renowned for its impressive performance, stylish design, and advanced engineering. One of the most significant components powering these vehicles is the MA104 4-liter flat-six engine, which is part number 031 111 104 0040. This engine, built specifically for the Carrera S and Carrera 4S models, delivers an engaging driving experience with its inspiring power and time-honored character.
Beneath the bonnet of the 911 991, the MA104 engineBlock is a marvel of modern engineering. Its size is 4.0 liters, with an official displacement of 3,996 cc. The engine is a naturally aspirated inline-six configuration, bearing a bore x stroke measurement of 100.2 x 94.4 mm. This enables the engine to generate a maximum power output of 400 PS (395 bhp) accompanied by a peak torque of 387 lb-ft (525 Nm) at 6,500 rpm.
The intake penetrates deep into the cylinder block to access the four valves per cylinder, ensuring ample air is drawn into the combustion chamber for peak performance.

Variocam Plus, an advanced valve control system, enables a broader powerband by adjusting the timing and duration of the intake and exhaust valves in real-time to respond efficiently to driving demands. Additionally, the engine inherits the VarioCam system's ability to move the intake camshaft to optimize intake valve lift depending on engine speed and load conditions.
The MA104 4.0L engine is fitted with Direct Fuel Injection, which delivers fuel directly to the combustion chamber with utmost precision. This technology, coupled with Porsche's unique Lean Burn technology makes the engine incredibly responsive and fuel-efficient.
With its ability to deliver an enthralling and exhilarating driving experience, this engine embodies the essence of the Porsche 911 991 series.
