Show original supplier description
This kit is engineered to improve upon the renowned OEM CSL airbox, offering a 20% increase in airflow compared to the standard factory airbox and even a marginal improvement over the original CSL unit. It aims to deliver both performance gains and a more engaging sound symphony for enthusiasts. This complete kit includes all necessary components for a full transformation, with the exception of a required electronic tune. Specifically, an Alpha N tune is mandatory for proper operation of this intake system. Please note that for US vehicles produced after September 2004, the original PCV recirculation hose will need to be reused and modified; the included silicone hose will require a fitting to be removed and then spliced into the factory PCV hose to maintain PCV functionality. This product is not for sale or use in the state of California on any pollution-controlled vehicle, as per the California Air Resources Board. The kit is compatible with BMW E46 M3, Z3 M Coupe/Roadster, and Z4 M Coupe/Roadster models equipped with the S54 3.2L engine. It also comes with a Lifetime Replacement Program.
