Ultimate quality - Real world proven

Our VAC CSL Carbon Fiber Airbox kits are designed to replace the OE factory airbox, improve performance and weigh only a few lbs!
Our comprehensive kit along with the beautiful craftsmanship of our CSL-Style Air Box makes for an excellent combination when performance and exclusivity is key: This is more than an air-intake; double digit power gains, artisan craftsmanship, and sound like you have never heard propel your car into a whole new level of performance and esthetics.

No longer do you have to purchase an airbox overseas; or battle with low quality kits that are far from comprehensive.
Our quality is unrivaled, with excellent fitment and durability.
Our kit is specifically made for converting a non-CSL E46 M3 into a near perfect replica, with even more flexibility so you don't have to hunt down the expensive parts from BMW that are no longer available, or simply too costly.

Along with a VAC flash to you ECU, you can achieve the exotic, naturally aspirated performance you crave on your S54! Reliability and performance live in harmony

    CSL Airbox Kit
    Owners of the E46 M3 and S54 powered vehicles know; it has been a challenge for many tuners to improve on BMWs factory power output and delivery.
    The CSL was BMWs ultimate achievement with the S54 offering true motor-sports performance on the street, or dominance on the track.
    As an exact-replica of OEM, our CSL box utilizes the 200mm intake diameter, internal BMW Motorsport panel filter (click above to add), fitting for air temp sensor (included), and elimination of the mass airflow sensor as on the CSL.
    This is an excellent match for our "CSL Killer" or Race engines. Can be fitted to the Z3M with minimal modification.

VAC Tech Notes:
The CSL airbox requires Specialized ECU tuning if standard BMW ECU is to be retained.
Compatible with custom BMW CSL software and also custom software that enables "Alpha/N" mode.
Note that we do not offer an HFM/AFM style airbox at this time as we feel the Alpha/N style tuning offers such an improvement in performance.
