INFINITY DESIGN S85 CSL CARBON PLENUM & CSL INTAKE KIT FOR BMW E60 M5 / E63 M6

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 market something very special for what is essentially one of the last of the truly great naturally aspirated engines.

Infinity Design therefore went out of it's way to give the enthusiast S85 owners something very special.

The 100% pre preg carbon fibre plenum was designed in CAD software using accurate 3D scans of the 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 system.

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.

At the core of the design is the 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.

There are 4 main components:
Main Plenum
Throttle body bosses
Velocity stacks
Side inlets
