Eventuri CSL Style Carbon Fibre Airbox Intake Plenum for BMW Z3 M S54 (EVE-Z3M-ABX) Alpha-N Ready

Eventuri S54 Z3M Carbon Induction Plenum Upgrade | EVE-Z3M-ABX

Give your Z3M S54B32 the soundtrack and response it deserves with Eventuri’s carbon composite induction plenum. Handcrafted entirely from pre-preg carbon by the same motorsport-grade specialists behind Formula 1 bodywork, this system delivers factory-quality fit with a truly special driving experience. The trademark ITB roar arrives as you open the throttle, yet cruising remains refined. It is the ultimate intake conversion for enthusiasts chasing that CSL-inspired character without compromise.

We have fitted this system on our own builds and for customers, and the feedback is consistently outstanding. The quality of the weave, the precision of the moulding and the way the car picks up revs make this one of those upgrades you look forward to every single drive.

Typical calibration changes

• Full-load fuelling optimisation
• High-load ignition targets
• Part-load ignition refinement
• Minimum ignition floor adjustment
• Torque model updates
• 250 km/h limiter removal
• Dyno limiter removal usually set near 6,300 rpm
• Sport button memory retained when set prior to key-off
• Normal and Sport pedal maps refined for smoother control
• VANOS inlet and exhaust optimisation
• Throttle request maps revised to achieve full opening
