CSF Charge-Air-Cooler Manifold – BMW Gen 1 B58

CSF B58 Super Manifold – Ultimate Cooling & Performance Upgrade for Gen 1 B58 Powered BMWs

With the increasing popularity of Gen 1 B58-powered BMWs in competition and high-performance builds, demand for reliable, motorsports-grade components is at an all-time high. The CSF B58 Super Manifold is engineered to address the OEM manifold’s limitations and provide the largest feature set in the industry for power, reliability, and cooling efficiency—making it the go-to solution for enthusiasts pushing 600+ horsepower and beyond.

Why Upgrade from the OEM Manifold?

While the factory charge-air-cooler manifold performs adequately on stock or mildly modified vehicles, it struggles under increased boost, fueling, and tuning demands. High intake air temperatures (IATs) due to heat soak cause power loss, timing pulls, and even “limp mode” during prolonged track or motorsport use. Additionally, the OEM manifold’s plastic core and crimped tanks are prone to failure at high boost levels, limiting performance and durability.

Proven Results in Real-World Testing:

• Achieves ~30°F lower intake air temperatures compared to OEM

• Reduces pressure drop for improved airflow and turbo efficiency

• Prevents limp mode during extended hard driving or racing

• Demonstrates +26 whp and +11 wtq gains on a Stage 2 bolt-on build (~400 whp)

• Gains scale with increased power levels

Industry-Leading Features:

• High-Performance Bar & Plate Air-to-Water Intercooler Core – Motorsports-grade with double the cooling capacity of OEM (12 rows vs. 6 rows)

• Engineered with CFD (Computational Fluid Dynamics) for optimized airflow and heat rejection

• Integrated Air Divider for even airflow distribution across the core

• Slotted Mounting Holes for easier throttle body installation

• Spin-Off Oil Filter Access – No need to remove manifold during oil changes

• Counter Balanced Design for optimized airflow dynamics

• Sensor Pad with Three 1/8” NPT Ports for additional monitoring options

• Optional Top Feed Fuel Rail & Individual Injection Ports – Comes pre-plugged, ready for port injection upgrades

• Ports for Nitrous or Methanol Injection on each runner for precise spray control

• Breather Ports on Manifold Water Connections for simplified air bleeding

• KIYLEX Thermal Rejection Spacer Included – Reduces heat transfer and lowers manifold temps by up to 15%

• Plug & Play Installation with no modifications needed

• Comes with Detailed Installation Kit & Hardware – Includes 32 components with pictorial instructions

• Finished in Raw Billet Aluminum by world-leading machinists at Custom Plenum Creations (Australia)

• Optional Powder-Coating and Thermal Rejection Finishes Available
