Improve the performance of your Z3M S54 with the Rogue Engineering Performance Intake Boot. Made from high quality, 4-ply silicone, it removes the turbulent ribs of the factory plastic elbow and smoothes the air intake path to the intake manifold. This replaces OEM # 11617830358 also known as an "Air Duct"
Smooth, uninterrupted airflow.
The Z3M S54 boot fits 2001-02 Z3M vehicles equipped with S54 engines (US and Euro, NOT CSL). This will NOT fit 1999-2000 S52 equipped Z3Ms. This fits OEM intakes or aftermarket ones that use the factory, plastic intake elbow. This is NOT designed to fit aftermarket intakes that have been designed with their own elbow.
The intake boot includes replacement clamps, as the factory ones are not large enough to fit around the larger OD of the replacement elbow.
