CSF BMW S58 "No Limit" Billet Air-To-Air Competition Manifold #8402

Push beyond the limits of the S58 platform with the CSF “No Limit” Billet Air-To-Air Competition Manifold, engineered for extreme power builds and record-breaking performance. Developed in collaboration with Custom Plenum Creations (CPC), this fully CNC-machined billet intake manifold removes the factory charge cooler limitation, unlocking significantly greater airflow potential and enabling the use of larger, more efficient front-mounted intercooler systems. Designed for serious high-horsepower applications, this manifold delivers the strength, precision and flow required for builds targeting 1500+ WHP and beyond.

Key Features:

• Fully CNC-machined 6061 billet aluminium construction

• Designed for extreme power S58 builds (1500+ WHP capability)

• Removes OEM charge cooler restriction for maximum airflow potential

• Supports both Air-to-Air and Air-to-Water intercooler setups

• Optimised plenum volume and runner design via CFD analysis

• Integrated velocity stacks for improved airflow and cylinder efficiency

• High-pressure O-ring sealed design (100+ PSI capable)

• Larger 77mm S55 throttle body compatibility

• Integrated sensor ports and vacuum sources

• Includes billet fuel rail for port injection (6 injector setup)

• Modular ports for secondary injection, nitrous or methanol systems

• Includes CSF Thermal Rejection Spacer (reduces intake temps)

• Supplied with full hardware kit and installation components

Engineered for Maximum Airflow & Power

Unlike traditional intake manifolds that integrate a charge cooler, the CSF “No Limit” design removes this restriction entirely. This allows for significantly larger intercooler cores to be utilised, dramatically improving charge air cooling and supporting higher boost levels without compromise.

The result is:

• Increased airflow capacity

• Improved intake air temperatures (IATs)

• Greater tuning headroom

• Enhanced high-RPM performance

Advanced Billet Design & CFD Optimisation

Each manifold is precision-machined from solid 6061 aluminium and engineered using advanced CFD analysis to ensure:

• Even airflow distribution across all cylinders

• Reduced turbulence and restriction

• Improved cylinder scavenging

• Consistent power delivery at extreme boost levels

The integrated velocity stacks further refine airflow, maximising efficiency and top-end power.

Race-Proven Performance

The CSF “No Limit” manifold has already proven itself on some of the fastest S58-powered BMWs in the world. At Texas 2K 2026, leading builds utilised this manifold to achieve:

• 7-second quarter mile performance

• Record-breaking BMW drag results

• Consistent high-power reliability under extreme conditions

This real-world validation highlights the manifold’s capability in true high-performance environments.

Motorsport-Ready Functionality

Designed for advanced builds, the manifold includes multiple features for serious tuning applications:

• Top-feed port injection capability (6 or 12 injectors)

• Modular ports for nitrous or methanol injection

• Dual integrated sensor pads for additional data monitoring

• Multiple NPT ports for custom setups

• Billet oil filter housing adapter for improved serviceability
