Further Information
The CSF Gen 1 B58 Charge Air Cooler Manifold brings industry-leading motorsports-grade cooling to F-Chassis BMW platforms. Built on the proven design of CSF's acclaimed Gen 2 "Super Manifold" with refinements for superior fit and finish, this raw billet manifold delivers the all-in-one solution for modified and competition vehicles pushing 600+ horsepower.
OEM manifolds struggle under bolt-on modifications, turbo upgrades, and demanding track conditions, leading to heat soak, timing pull, and limp mode activation. The CSF manifold eliminates these weaknesses through precision engineering and extensive dyno validation.
Key Features:
- Raw billet construction with application-specific engineering for Gen 1 B58 compatibility
- Integrated top-feed port injection with extruded Radium Engineering fuel rail and anodized CNC injector hats
- Individual 1/8" NPT nitrous and methanol injection ports on each cylinder runner for maximum spray control
- Three-port vacuum and parameter pad for additional sensor mounting and vacuum sources
- Recessed oil filter access with counter-balanced CFD-optimized airflow design
- Air inlet divider for consistent cooling performance and heat rejection
- Proven resistance to heat soak in extreme motorsports conditions
Performance Notes:
- ~26whp and 11wtq gain on stage 2 bolt-on vehicles (400whp baseline)
- ~30°F reduction in intake air temperatures versus OEM manifold
- Faster IAT recovery and reduced turbo system stress at higher boost targets
- Validated on vehicles exceeding 1000whp in drag racing and time attack competition
- Proven at Pikes Peak International Hill Climb, Global Time Attack, and Texas 2K drag racing
Includes:
- CSF raw billet charge air cooler manifold with welded inlet divider
- Extruded AN-8 fuel rail with Radium Engineering fittings
- Six anodized CNC machined injector hats for short-height injectors
- Complete installation hardware kit with vacuum port plugs
Motorsports-proven cooling for Gen 1 B58. Maximum power. Maximum reliability. Maximum performance.
