Investing in cylinder head porting for your high-performance BMW engine enhances airflow efficiency for improved engine power, throttle response, and overall performance. By optimizing the intake and exhaust passages, porting reduces restrictions, allowing the engine to breathe better and generate more horsepower and torque. We only use CNC equipment, ensuring that each port is machined to the exact same specifications, providing uniformity across all cylinders. This precision is crucial for maintaining consistent performance and efficiency. Service Overview: Multi-Angle CNC Porting Porting involves modifying the intake and exhaust ports of the cylinder head to improve the flow of air and fuel into the combustion chamber and the expulsion of exhaust gases out of the chamber. The first step of this process involves assessing the cylinder head's current flow characteristics to identify any restrictions or turbulence. Then, material is carefully removed from the walls of the intake and exhaust ports to simultaneously enlarge them and improve their shape for optimal flow. The result is a smoother, more direct path for air and fuel into the combustion chamber, as well as a smooth, more efficient path for exhaust to flow out of the combustion chamber.  Because we use CNC machining, we can ensure each port is exact and even across the cylinder head. This means airflow is balanced across all cylinders. Benefits of porting include increased airflow for more power and improved throttle response.  BMW N55 Applications: 1 Series 2010-2013     E82/E88     135i 2012-2016     F20/F21     M135i 2 Series 2014-2016     F22/F23     M235i 2016-2018     F87     M2 3 Series 2010-2015     E90/E91/E92/E93     335i 2012-2015     F30/F31/F34     335i 2015-2016     F30/F31     340i 4 Series 2013-2016     F32/F33/F36     435i 2016     F32/F33/F36     440i 5 Series 2010-2016     F10/F11     535i 2010-2017     F07     535i GT 6 Series 2011-2018     F12/F13/F06     640i Gran Coupe 7 Series 2012-2015     F01/F02     740i / 740Li X1 Series 2013-2015     E84     X1 xDrive35i X3 Series 2011-2017     F25     X3 xDrive35i X4 Series 2014-2017     F26     X4 xDrive35i 2016-2017     F26     X4 M40i X5 Series 2011-2018     E70/F15     X5 xDrive35i X6 Series 2011-2019     E71/F16     X6 xDrive35i ALPINA N55 Applications: B3 Series 2013-2018     F30/F31     B3 Bi-Turbo B4 Series 2014-2019     F32/F33     B4 Bi-Turbo
