Selection and installation

Confirm turbo inlet size, pipework, sensor provision and available clearance before ordering. Inspect all clamps and connections after installation and verify that no debris can enter the compressor inlet.

Professional installation and calibration review are recommended where the part changes airflow measurement, compressor-inlet restriction or the surrounding intake layout.

Before ordering

Review the product options and included parts, then contact MLAB with the vehicle VIN and current modifications if the exact combination is uncertain. MLAB by Boost and Tune can assist with product selection, workshop installation and dyno calibration for supported BMW applications in Melbourne.
