Charge Boost Pipe Kit for BMW S55 F80 M3 F82 F83 M4 2014–2020

This kit features an enlarged internal diameter compared to the original intake pipe, significantly minimizing airflow restriction. The factory component often creates air turbulence, reducing flow and overall performance. The original plastic construction is prone to breaking at the mounting flange or cracking, which is why this kit replaces it with durable aluminum pipes to ensure optimal tightness.

The components are connected using a silicone reducer that boasts quadruple reinforcement and a wall thickness of 5 mm.

Includes 1/8" NPT ports/plugs for methanol injection or for connecting an intake air temperature sensor.

• Pipe made of 6061 aluminum, serving as a replacement for the OEM pipe.
• Aluminum connectors replace the faulty plastic pipe, which may fail under increased boost pressure.
• Enlarged diameter and smooth, restriction-free flow help reduce turbulence and maximize airflow.
• All connection fittings are CNC machined.

Kit contents:

• Powder-coated black aluminum connectors:
  1x 76 mm: 1x 1/8 NPT port/plug
  2x 57 mm: 1x 1/8 NPT port/plug
• Silicone connectors: 1x 87 mm, 2x 57 mm
