BMW G01 X3 M40i, G02 X4 M40i (B58D Engine Version) Carbon Intake

The Eventuri B58 intake system represents a complete engineered solution balancing unrestricted airflow with superior cold air saturation. Meticulously developed from prepreg carbon pieces to double-layer heat shields, this system demonstrates precision craftsmanship and aerodynamic innovation for the B58 platform.

Key Features:

• Patented carbon fiber housing maintains laminar flow conditions and reduces turbo drag
• Double-layer main and secondary heat shields with reflective silver and absorptive black surfaces
• Continuous curve carbon scoop efficiently channels intake air to factory duct openings
• Integrated carbon filter housing and MAF tube reduce internal interfaces for smoother airflow
• CNC-machined MAF boss and laser-cut mounting brackets ensure precision fit
• High-flow double cone air filter maximizes airflow capacity

Performance Notes:

• +12-15hp across the RPM range
• +14-18ft-lb torque increase
• Over 90°C temperature drop across main heat shield validated by thermal imaging

Includes:

• Prepreg carbon filter housing with integrated MAF tube
• High-flow double cone air filter
• Aluminium cowl for smooth airflow entry
• Prepreg carbon scoop and filter shroud
• Double-layer main and secondary heat shields
• Laser-cut mounting brackets and installation hardware
• Installation guide

Cold air. Clean flow. Real power. Built for the B58.
