Turner Motorsport CSL Style Intake in Carbon - S54

CSL-inspired carbon fibre airbox for BMW S54 engines

Bring the legendary CSL induction experience to your S54 with this motorsport-grade carbon fibre airbox. Developed and flow-tested by Turner, this high-performance carbon induction kit delivers exceptional airflow and that unmistakable straight-six intake roar, transforming response and theatre on road and track. It is a cost-effective alternative to the ultra-rare factory CSL unit while retaining compatibility with genuine CSL ancillaries.

Performance and quality you can feel

• Flow bench verified to move almost 20 percent more air than the standard M3 intake, promoting stronger top-end breathing and sharper throttle response when mapped correctly.

• Uses the factory CSL filter element and OEM CSL intake boots for dependable sealing and OEM-level integration.
• Iconic induction sound that enthusiasts want from an S54 carbon airbox upgrade.
• Developed through rigorous research and testing for reliability and repeatable results.

We have fitted this on customer cars and the feedback has been outstanding. The combination of improved breathing, crisp response and addictive intake noise makes this one of the most rewarding upgrades for any S54 owner.
