CSF has officially released its latest innovation for the BMW B58 and S58 platforms - the "No Limit" Billet Air-to-Air Competition Intake Manifolds (CSF #8401 & #8402) supporting 1500+ wheel horsepower.
Developed for extreme performance applications and unveiled following a record-breaking Texas 2K26, these manifolds represent a major leap forward in intake design for high-powered BMW builds.
At Texas 2K26, Tom Wrigley Performance’s G80 M3 xDrive became the fastest BMW in the world, running a 7.674-second quarter mile at 183.94mph running the CSF #8402 S58 “No Limit” manifold.
Alongside this, multiple S58 builds using the same platform achieved 7-second passes, proving the concept under real-world, high-temperature race conditions.
Why CSF Developed the “No Limit” Manifold
As B58 and S58 builds continue to push further into four-figure horsepower, traditional intake manifolds have become a major restriction.
Factory-style designs limit:
- Intercooler size
- Airflow efficiency
- High-boost performance
CSF’s approach removes those limitations entirely.
By eliminating the integrated charge cooler, the “No Limit” manifold allows for:
- Larger, more efficient front-mounted intercoolers
- Air-to-air or air-to-water flexibility
- Significantly improved airflow and plenum performance
The result is a system designed specifically for maximum performance with no compromise.
Engineered for Extreme Performance
This is not an adapted OEM design, it’s a purpose-built, race-ready solution. Manufactured from solid 6061 billet aluminium and CNC-machined by Custom Plenum Creations (CPC), the manifold is built to handle the demands of serious power.
Key engineering features include:
- Optimised plenum volume for high boost applications
- Integrated velocity stacks for smooth airflow distribution
- CFD-tested runner design to eliminate imbalance
- O-ring sealed construction capable of handling 100+ psi
Every detail is focused on delivering consistent airflow, strength and reliability at extreme power levels.
Key Features of the CSF 8401 & 8402
- CNC-machined 6061 billet aluminium construction
- 77mm throttle body compatibility (S55 TB) for increased airflow
- Top-feed port injection capability (6 or 12 injectors)
- Modular ports for nitrous, methanol, or additional fuelling
- Integrated sensor ports for advanced monitoring
- Thermal rejection spacer (reduces intake temps by up to 15%)
- Designed for 100+ psi boost pressure
The S58 version (CSF #8402) also includes a billet oil filter housing adapter for improved access and serviceability.
Proven by Tom Wrigley Performance
The standout validation for this new release comes from Tom Wrigley Performance’s G80 M3.
Producing around 1650whp, the car achieved:
- Fastest BMW in the world
- 7.674-second quarter mile
- 183.94mph trap speed
At this level, airflow efficiency and temperature control are critical and this manifold plays a key role in enabling both.
Air-to-Air & Air-to-Water Flexibility
One of the biggest advantages of the “No Limit” platform is its flexibility.
At TX2K26:
- Tom Wrigley Performance ran an air-to-water setup
- GTP Motorsport successfully ran air-to-air setups
Both approaches delivered 7-second performance, giving builders the freedom to choose the right configuration for their goals.
