This listing is built around aFe POWER part number 46-53241 for the OER Series 2001–2006 BMW 3 2001–2006 Series (E46) / Z4 (E85/E86) 2003–2008.
The value of a vehicle-specific component is in fitment, material choice, intended function and compatibility with the surrounding system. Those details matter more than a generic promise of performance.
What This Means on the Car
A component should be evaluated as part of the complete vehicle. The same part can be highly worthwhile on one build and unnecessary on another depending on use, supporting modifications and the limitation being addressed.

Fitment can differ by engine, drivetrain, trim, factory equipment, emissions configuration and production date. Match the part number above to the vehicle before installation; where aFe publishes SKU-specific installation or emissions requirements, those requirements take precedence.
