Further Information
The CSF Gen 1 B58 Charge Air Cooler Manifold is an all-in-one cooling solution engineered for modified and motorsports-focused F-Chassis BMWs. Built on the proven platform of CSF's Gen 2 B58 "Super Manifold" with design refinements for Gen 1 applications, this manifold eliminates the limitations of OEM systems that struggle under boost, tuning, and demanding racing conditions.
Extensive dyno testing with VF Engineering demonstrated ~30°F IAT reduction compared to OEM, preventing heat soak and limp mode activation in time attack, drag racing, endurance, and drifting applications. Stage 2 testing showed +26whp and +11wtq gains with proven performance scaling to over 1000 whp.
Key Features:
- ~30°F intake air temperature reduction versus OEM manifold
- Faster IAT recovery time with less pressure drop across core
- Top-feed port injection with included Radium Engineering AN-8 fuel rail
- Individual 1/8" NPT nitrous/methanol injector ports per cylinder runner
- Anodized CNC machined injector hats (qty 6) for short-height injector compatibility
- Vacuum and parameter measurement ports integrated into manifold inlet
- Reduces turbo system duty cycle stress for higher boost targets
- Tested and proven across Pikes Peak Hill Climb, Global Time Attack, and 1000+ whp drag racing
Performance Notes:
- ~26whp and 11wtq increase on stage 2 400whp baseline
- Performance delta increases with higher power levels
- Proven on vehicles exceeding 1000 whp
- Eliminates limp mode activation in prolonged demanding conditions
Includes:
- CSF Gen 1 B58 Charge Air Cooler Manifold assembly
- Extruded aluminum AN-8 fuel rail with Radium Engineering fittings
- Six anodized CNC machined injector hats
- All required installation hardware
- Available in 20+ custom finish options including DLC, anodized, thermal, and color-changing coatings
Proven reliability for motorsports extremes. Superior cooling for serious power.
