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.

Excellent book to truly understand LLM design patterns
Format: Paperback
I just finished reviewing Ken Huang's pocket book on LLM Design Patterns, and WOW what an amazing resource! This book is excellent if you want to truly understand how to create and enhance intelligent AI language models, all that in your pocket! Ken makes the difficult things seem surprisingly easy, and that's the real MAGIC. - How to prepare your data for training by making it extremely clean. Developing the brains: the practical aspects of training, optimizing, and maintaining your models. - Learn amazing prompting techniques (such as Chain-of-Thought and Tree-of-Thoughts) to improve your AI's reasoning and problem-solving abilities. Learn everything there is to know about RAGs so that your LLM can incorporate outside expertise. - It also delves into creating "agentic" AI that is capable of action and planning (not only simple plan and execute but also enhanced techniques like ReWoo!) Really, this feels like a useful toolkit, so Ken thank you for that resource Thanks, Idan Habler

A Broad Overview, But Light on Modern Fine-Tuning
Format: Paperback
I'm currently really interested in fine-tuning LLMs and recently completed my first LoRA-based fine-tuning on a quantized model. I came to this book looking for more detail on fine-tuning. While it touches on the topic, I found the content didn’t quite align with the current state of the field in 2025. Techniques like LoRA, QLoRA, and PEFT weren’t really covered, and the material leaned more toward what I think are older or lower level approaches. That made it harder to connect with what I’m actually working on. That said, when I shifted to other chapters — like the sections on prompt engineering techniques such as Chain of Thought (CoT) and Tree of Thought (ToT) — I found more value. These sections were clearer, and I picked up a few practical insights, like using few-shot examples that walk through the CoT reasoning process. That’s not something I’ve tried before, and I can see how it might help smaller models that struggle with any type of reasoning tasks. Overall, the book feels more like a broad overview of all LLM concepts. For someone exploring many topics across the LLM ecosystem, it offers a wide-ranging introduction. But for readers like me who are actively trying to learn and apply techniques like fine-tuning and quantization, it may leave you wanting up-to-date guidance.

Loved it
Format: Paperback
I’ve easily read dozens of tech books. I liked this one a lot. Sure, there were boring parts, but most of it was engaging, especially on dry subjects. I previously read “How AI Works” and found this more informative and way more enjoyable. I got through the 700 pages in about 5 weeks while also learning about probability and linear algebra from other books and online sources. I’d love to read something more advanced by the author, maybe getting into more modern applications. I feel more comfortable with the subject and feel I am now ready to conquer more advanced texts. I initially picked this up to give me some background before reading “How to Build a LLM (from scratch)”. I’ve ordered an intermediary Deep Learning with Python book as well, but wouldn’t mind a more advanced theory book to accompany these books. I’ll definitely be rereading sections of this book to further familiarize myself with topics like backpropagation. Highly recommend if you’re looking for a gentle, but broad introduction to the topic.

A Good Place to Start Learning AI
Format: Paperback
Diving into the world of artificial intelligence can feel like stepping into a vast, uncharted ocean, and if you're looking for a reliable vessel to navigate these waters, this book is an excellent choice. However, I must be candid—this journey is not for the faint-hearted or those hoping to breeze through. The subject of AI, with its complex algorithms and intricate theories, is notoriously challenging. You won't find yourself flipping pages at a rapid pace, as this is not a title designed for speed-reading. Instead, it demands your full attention and a willingness to engage deeply with the material. At the heart of AI lies mathematics—a fundamental pillar that underpins the entire discipline. This book, while comprehensive, offers only a glimpse into the mathematical framework that drives artificial intelligence. But don’t be disheartened by this. Think of it as a solid foundation, a primer that will arm you with the essential concepts needed before you delve deeper into the more advanced mathematical intricacies elsewhere. When you do eventually tackle those more complex equations, you'll find yourself better equipped, with a clearer understanding of the principles at play. I should also mention that I'm no stranger to Andrew's work. Having explored some of his other writings, I can confidently say that he possesses a unique flair for communication. His ability to distill complex ideas into accessible language, without losing the essence of the subject, is truly commendable. Andrew writes with a certain finesse and sophistication that makes even the most daunting topics seem approachable. His style is not just informative, but also engaging, with a touch of elegance that sets his work apart from others in the field. In summary, while the path to mastering AI is undeniably steep, this book serves as an invaluable guide. It’s not just a starting point; it’s a beacon for those who are serious about understanding the intricacies of artificial intelligence. Be prepared to invest time and effort, and in return, you'll gain a solid foothold in a subject that is as fascinating as it is complex.
