EVENTURI | BMW G29 Z4 M40i B58 Carbon IntakeThe 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.

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

The Eventuri Z4 B58 intake system consists of a number of components engineered to perform a specific purpose and fabricated to the highest of standards. We use 100% pre-preg carbon fiber with no fibreglass which means we can achieve a smooth internal surface to maintain smoother airflow. Here are the details for each component and the design ethos behind them:

Each intake system consists of:

• Carbon Fiber Airbox with Dual Feeds
• Bespoke High Flow Dry Cone Filter
• Carbon Fiber Inlet Tube with 111mm opening ID
• CNC Machined Temperature Sensor Mount
• CNC Machined Breather adapter
• Heat Shield with Gold Reflective Backing
• Laser Cut Stainless Steel Brackets
• Silicon Coupler with OEM Specification Clamps

Includes:

• Dual feed carbon fiber airbox with heat shield
• Carbon fiber inlet tube with CNC machined fittings
• Bespoke high-flow dry cone filter
