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 M52TU Applications: BMW 3 Series 1998-2000     E46     320i / 320Ci 1998-2000     E46     323i / 323Ci 1998-2000     E46     328i / 328Ci BMW 5 Series 1998-2000     E39     523i 1998-2000     E39     528i BMW Z3 Series 1998-2000     Z3     2.0i / 2.8i
