Description
The Infinity Design BMW E60 M5 One-Piece Carbon Plenum is our flagship S85 induction system – a modular, 100% pre-preg carbon fibre masterpiece designed to combine breathtaking sound with real performance gains. Inspired by the legendary BMW E60 M5 CSL prototype, this plenum goes beyond being a noise upgrade and delivers increased airflow, modular upgrade paths, and stunning engine bay aesthetics for one of the greatest naturally aspirated V10 engines ever built.
Fitment:
-
BMW E60 M5 (2005–2010) – S85 V10
Performance Benefits:
- Unmatched induction sound – CSL-inspired resonance at high RPM
- Dyno-proven power gains and improved real-world acceleration
- Increased usable torque and faster 60–130 mph times
- Modular design allows multiple upgrade paths
- Stronger throttle response with improved airflow efficiency
Design & Development:
- CAD-designed using precise 3D scans of the S85 engine, OEM plenums, and engine bay
- One-piece carbon plenum increases internal volume over OEM twin-plenum design
- Modular construction allows OEM side inlets or upgrade to CSL large inlets
- CSL side inlets are 100% larger in cross-sectional area than OEM for maximum airflow
- Velocity stacks feature a 10% larger opening than OEM and face directly towards the inlets for optimized air distribution (stock orientation available on request)
- CNC-machined throttle body adapters bolt directly into the plenum, ensuring a perfect and durable seal
Upgrade Options:
- Plenum Only: Fits with OEM side inlets or any intake compatible with OEM plenum
- CSL Side Inlets Upgrade: Over 100% larger than stock, modeled after the original CSL design
- Full CSL Intake Kit: Includes plenum, CSL inlets, and larger inlet tubes for maximum performance
- Velocity Stacks: Carbon with aluminum base plates, designed for maximum flow efficiency
Performance & Sound Testing:
-
Reports from pre-production systems confirm:
- Sharper throttle response
- Improved torque delivery across the rev range
- Faster 60–130 mph times
- Increased peak power
- Induction sound is described as unmatched, creating an intoxicating CSL-style howl at high revs
Construction & Finish:
- 100% pre-preg carbon fibre – lightweight, durable, and heat resistant
- Available in gloss or matte carbon finishes
- OEM fitment for seamless installation
Requirements:
-
AlphaN ECU tuning required
The Infinity Design E60 M5 One-Piece Carbon Plenum is more than an intake – it’s an engineering showcase and a true homage to the CSL concept, offering S85 owners a unique opportunity to unlock the full character of their V10.
