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. 

infinity did not want to make just make another carbon plenum which replaces the OEM for noise alone.
Like the rest of their range they 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 100-200 km/h 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
Lid

Fitment
The fundamental problem with one piece plenums is that they are very difficult to fit as the throttle bodies are at a 120 degrees angle to one another unlike the S65 engine where they are at a 180 degree angle and the plenum fits directly downwards on top of them.  A solid one-piece plenum causes major issues when attempting to fit with the rubber boots not seating correctly onto the adaptors on the plenum which lead to major air leaks.  The system also requires considerable force to seat correctly.
The Infinity Design plenum allows the throttle body bosses to first be attached to the rubber boots, the main plenum is placed onto the adapters, the velocity stacks are then attached, side inlets installed and lid installed leading to a leak free and simple process.

By keeping the main frame, throttle body bosses, velocity stacks, side inlets and lid separate a logical and simple process can be taken to fit the system giving no risk of overlapping of the throttle body boots which leads to air leaks and having to force the plenum into position

Upgradability
By allowing all of the parts to be separate it allows the end user to change the velocity stacks to shorter types to give a higher rpm biased power delivery.
The side inlets can be changed from the OEM style to the CSL Style which give a significantly larger opening leading to a large volume high flow intake system.

Resistence to Failure
It has been long known that carbon plenums suffer from internal failures.  The most common issue is the velocity stacks break away as they are often glued.  Over time the adhesive weakens with heat cycles and vibrations.  Not only is the entire plenum wasted but can cause major catastrophic engine damage as the broken carbon shards entire into the combustion chamber.
The Infinity Design system has one piece velocity stacks which are bolted through the plenum into the throttle body bosses.  There is no chance of failure.

Lower Cost
Since all of the parts of the plenum are individually manufactured and supplied there is no expense of assembly which poses a significant cost in carbon parts.  Jigs are required for exact placement of parts with adhesive, drying times and cleaning required which all add time to the manufacturing process leading to a higher overall price.
Given how complex our system is, the cost is very reasonable.

The velocity stacks were lightly redesigned with a larger and longer opening with them all facing the significantly larger side openings rather than away from the path of the air.

Solid Floating Shelves 🛠️🏠
Color: Black, Number Of Shelves: 4, Size: 15.7in
I have installed four sets of the black floating shelves in my office. They are made of high quality materials, featuring a sophisticated black woodgrain finish with a natural texture. Supposedly, each unit can handle up to 22 pounds, though I would not recommend testing that limit with your vintage bowling ball collection if you value your flooring. They are awesome. The value is good for a set of two. Each shelf measures 22x7x1 (56x17x3 cm) inches, providing a decent amount of storage for books or decor. The installation was straightforward since the hardware for multiple wall types was included. They work well in the kitchen for spices or in the bedroom for personal belongings. One tip for a secure fit: use a level during installation and make sure the bracket is flush against the wall before sliding the shelf on, or your photos might look like they are sliding off a mountain 📐 These shelves offer a clean, modern look and stay stable once mounted correctly. They are a practical choice for adding functional display space to any room 🖼️

Good looking shelves and easy install - skip the included drywall anchors
Color: Black, Number Of Shelves: 2, Size: 22in
I installed these shelves in a bedroom to get things off my dresser and some decor. Once mounted they look really nice. The black finish looks clean and modern and they blend in well with the room. Installation was pretty straightforward. The metal bracket mounts to the wall first and then the shelf slides over the bracket. As long as you take your time lining things up it’s a simple project. One thing I strongly recommend is not using the white plastic self-drilling drywall anchors that come with the kit. I’ve used that style before on other projects and they tend to strip out easily and leave larger holes in drywall. I used better anchors instead and the shelves mounted much more securely. The rest of the hardware worked fine and once installed the shelves feel solid and hold items well. Pros - Clean modern look - Easy installation - Feels solid once mounted - Good size for books or decor Cons - The small level included isn’t very accurate — use your own level - One of the metal brackets was slightly bent out of the box but straightened out easily Helpful tip: Use your own level and better drywall anchors if you have them. It makes installation easier and the shelves will mount much more securely. Final thoughts: For the price these are nice looking floating shelves that install easily and work well for light storage and decor.
