Description
Take your high-performance BMW or Supra build beyond limits with the CSF B58 / S58 “No Limit” Billet Air-To-Air Competition Manifold. Developed by CSF in partnership with Custom Plenum Creations, this manifold is a purpose-built solution for extreme horsepower applications targeting 1500+ WHP and beyond.
Fresh off dominant results at TX2K 2026, this race-proven intake system has already powered some of the fastest BMW platforms in the world. Vehicles from Tom Wrigley Performance and GTP Motorsport achieved record-setting 7-second quarter-mile passes, proving the manifold’s capability under extreme heat and boost conditions.
Machined from solid 6061 billet aluminum, this competition manifold is engineered for durability, airflow efficiency, and consistent performance at the highest levels. By eliminating the factory integrated charge cooler, the CSF “No Limit” design removes airflow restrictions and allows for significantly larger front-mounted intercooler setups, whether Air-to-Air or Air-to-Water.
Advanced CFD optimization ensures balanced airflow distribution across all cylinders, while integrated velocity stacks maximize air delivery and improve top-end power. This results in increased horsepower, improved throttle response, and enhanced reliability in demanding racing environments.
Key Features:
- CNC-machined from solid 6061 billet aluminum for extreme strength and durability
- Supports high-performance builds exceeding 1500+ horsepower
- Internal velocity stacks for optimized airflow and improved engine efficiency
- CFD-optimized plenum and runner design for balanced cylinder distribution
- O-ring sealed design ensures leak-free performance under extreme boost
- Large throttle body flange designed for S55 throttle body (77mm vs 67–68mm OEM)
- Integrated sensor pads for additional data monitoring or vacuum sources
- Includes billet fuel rail for high-performance fueling systems
- Modular runner ports for secondary port injection, nitrous, or methanol injection
- Thermal rejection competition spacer reduces intake air temperatures and heat soak
- Compatible with both Air-to-Air and Air-to-Water intercooler configurations
- Track-proven with multiple 7-second quarter-mile record-setting vehicles
Design & Engineering
This manifold was engineered to overcome the limitations of traditional intake designs by relocating the charge cooling system externally. This allows for significantly increased intercooler core size and improved thermal efficiency, critical for high-boost applications.
With decades of billet manifold expertise drawn from platforms exceeding 2500+ HP, the collaboration behind this product ensures unmatched performance, structural integrity, and airflow precision. Every detail—from plenum volume to runner geometry—has been refined to deliver consistent power at extreme boost levels.
Proven Performance
Extensive real-world testing was conducted on leading S58-powered race cars, including record-breaking builds achieving 7-second quarter-mile times. Continuous feedback from top-tier racing teams has led to further refinements, making this manifold one of the most advanced solutions available for the BMW X58 platform.
