Design & Development
One of the most challenging intake systems to design and manufacture to date and our showcase product.
The BMW E60 M5 CSL has always captivated the hearts of S85 owners with the showcase being the single piece carbon plenum with larger side inlets running AlphaN software. It was never available as a part to purchase. We did not want to make just make another carbon plenum which replaces the OEM for noise alone. Like the rest of our range we wanted to give the enthusiasts something very special for what is essentially one of the last of the truly great naturally aspirated engines. Infinity Design therefore went the extra distance to give the enthusiast S85 owners something special.
The 100% pre preg carbon fibre plenum was designed in CAD software using accurate 3D scans of the engine and engine bay without the OEM plenum in place, 3D scans of both of the individual OEM plenums and then combined together to make a singular larger volume plenum.
At the core of the design is it's modularity. This is key both to the functionality, how the system is fitted, the multiple upgrade paths and also a lower price. No other product throughout the BMW aftermarket exists which is this complex and at the same time gives so many options and advantages.
OEM Side Inlets
Plenum Only where fitment is required to fit the OEM intake (or any intake which fits the OEM plenum).
Can be upgraded by removing the side inlets and fitting the larger CSL intake kit with the larger CSL side inlets
CSL Side Inlets & Full CSL Intake Kit
The CSL Side inlets are over 100% larger in cross sectional area than the OEM allowing for maximum airflow and very similar to the original CSL BMW designed for their 5.5L engine.
These side inlets are part of the CSL Intake kit which can be purchased as a complete kit with the plenum from the outset or purchased separately later as an upgrade with the larger inlet tube.
If you already have the Infinity Design intake kit the side inlets and inlet tubes on their own can be purchased allowing you to use the lower air filter housings, filters and clamps from the intake system.
Velocity Stacks
10 Velocity stack made from carbon with aluminum base plates are supplied. Similar to OEM velocity stacks with a 10% larger opening. The orientation has been changed to face the inlets. Stock orientation is also available upon request.
Throttle Body Adapters
10 CNC Machined throttle body adapters fit from below the plenum and bolt through the carbon plenum into the velocity stacks creating a thorough and strong seal.
PERFORMANCE & SOUND TESTING
The induction sound is beyond what has been achieved by the market. Mutiple reports of the intial pre production batch have shown more usable torque and improved 60-130mph times as well as improved power on dyno testing. Under bonnet looks are sensational.
