BMW G29 Z4 M40i B58 Carbon Intake

The Eventuri G29 Z4 B58 intake system is engineered to provide the turbo with a less restrictive flow path whilst maintaining low inlet temperatures. By combining a fully sealed dual-feed airbox design with a smooth carbon inlet tube, this system addresses the critical heat-soak challenge posed by the intake's proximity to the exhaust manifold.

Key Features:

• Dual cold air feeds from front bumper duct and wheel arch scoop reduce restriction
• Gold reflective heat shield minimizes radiative heat transfer from exhaust manifold
• Carbon inlet tube with 111mm internal diameter opening provides 82% larger cross-sectional area than stock
• Smooth tapering design ensures laminar airflow to turbo inlet
• Bespoke high-flow cone filter with larger surface area than stock panel filter
• 100% pre-preg carbon fiber airbox with no fiberglass for superior internal surface finish
• Internal splash guard protects filter from wheel arch spray
• Fully sealed construction keeps inlet air temperatures at minimum during road use

Performance Notes:

• +17-20hp across a large portion of RPM range
• +11-20ft-lb torque gains
• Independently dyno tested on B58 Supra with downpipe and tune
• Validated with hood closed to reflect real-world heat-soak conditions

Includes:

• Dual feed carbon fiber airbox with heat shield
• Carbon fiber inlet tube with CNC machined fittings
• Bespoke high-flow dry cone filter
• Temperature sensor mount and breather adapter
• Laser cut stainless steel brackets
• Silicon coupler with OEM specification clamps
• Installation guide

More power. More flow. Less heat. Built for the G29 Z4 M40i B58.
