Further Information
The Eventuri BMW G29 Z4 B58 intake system delivers a less restrictive flow path to the turbo while maintaining critically low inlet air temperatures. Engineered to address the unique challenge of the Z4's intake location adjacent to the exhaust manifold, this fully sealed system combines dual cold air feeds, advanced heat management, and precision carbon fiber construction to unlock measurable performance gains across the RPM range.
Key Features:
- Dual cold air feed design reduces inlet restriction without sacrificing sealed airbox benefits
- 100% prepreg carbon fiber construction with smooth internal surfaces for optimized airflow
- Carbon inlet tube features 109mm internal diameter—82% larger cross-sectional area than stock
- Gold reflective heat shield combats radiant heat transfer from adjacent exhaust manifold
- Bespoke high-flow dry cone filter with larger filtration surface area than OEM panel filter
- CNC machined components for temperature sensor and breather adapter integration
- Internal splash guard protects filter in wheel arch secondary feed
- Optional headlamp duct available for maximum cold air flow in race applications
Performance Notes:
- 17-20hp gain on BMW G29 Z4 M40i with B58 engine
- 11-20ft-lb torque increase across RPM range
- Independently tested on B58 Supra with downpipe and tune showing over 20hp gains in peak regions
Includes:
- Carbon fiber dual feed airbox with heat shield
- Carbon fiber inlet tube with 111mm starting diameter
- Bespoke high-flow dry cone filter
- CNC machined temperature sensor mount
- CNC machined breather adapter
- Laser cut stainless steel brackets
- Silicon coupler with OEM specification clamps
- Installation guide and hardware
