Eventuri BMW S54 Z3M CSL Carbon Fibre Airbox
Unlock the signature CSL intake sound and sharper throttle response for your BMW Z3 M S54 with the Eventuri CSL style carbon fibre airbox EVE-Z3M-ABX. Developed with leading motorsport composites specialists responsible for F1 bodywork, this intake uses 100 percent pre-preg carbon and cutting-edge manufacturing to deliver OEM level fit and finish with true performance benefits.
If you want the ultimate Z3M S54 intake upgrade, the Eventuri CSL carbon airbox is the benchmark. The induction roar is addictive, the mid-range punch is stronger and drivability remains smooth. Unlike exhaust upgrades that add constant cabin noise, an airbox transformation remains civil at idle and part throttle yet comes alive under load from around 2,500 rpm with that unmistakable CSL intake howl.
We have installed this kit and run it on our own builds. Customers consistently praise the quality, fitment and the way it elevates the driving experience on the S54-powered Z3M. It is the go-to performance intake for enthusiasts seeking CSL character, response and sound.
