The design goal for the M5 High Flow Cold Air Intake System was very specific: ensure that the powerful M5 engine is breathing plenty of cool oxygen-rich air for maximum performance under varying driving conditions. The system replaces the factory air-boxes with proprietary twin high flow air filters feeding large diameter intake plumbing, carefully designed to minimize air turbulence for maximum intake airflow. The filters are relocated outside of the engine compartment behind the front bumper and below the headlights insulating the intake from under-hood heat. Additional heat shields are incorporated in order to block the flow of power-robbing hot air passing over the radiator. The system also includes modified fog light trim rings for a ram air effect at speed. Ongoing development of the intake system revealed an interesting and significant discovery. Based upon exhaustive testing, it was determined that the stock location of the air temperature sensor within the Air Mass Meter was providing the engine management system with an artificially high reading, resulting in reduced power output. The culprit was determined to be ''heat soaking'' of the Air Mass Meter when an adequate flow of air was not passing over it, such as in daily stop and go traffic, producing a reading substantially higher than the actual temperature of the air entering the intake system. BMW's sophisticated engine management system would then automatically back off timing as a result, reducing available power until such time as the airflow cools the Air Mass Meter down. Therefore, the Dinan intake system includes an air temperature sensor relocation kit as part of the system, providing the engine management system with a more accurate reading and consistent performance. The newest iteration of the system goes back to its carbon fiber roots for a more showroom worthy appearance complete with an embossed Dinan logos instead of the inset Mylar decals that was prone to marring after decades of use.

Comfortable Ergonomic Chair for Long Workdays
Color: Black, Color: Black
I’ve been using this chair for my home office, and it’s been a great addition to my workspace. The seat cushion is thick and comfortable, even after several hours of sitting, and the mesh back keeps good airflow throughout the day. I especially like the adjustable headrest, which provides extra neck support when leaning back during breaks. Assembly was straightforward, the chair feels sturdy, and the wheels roll smoothly on my floor. The all-black design also gives it a professional look that fits well in any office setup. Overall, it’s a comfortable and affordable ergonomic chair that offers excellent value for the price.

Sturdy but uncomfortable
Color: Black
The seat itself is sturdy and easy to put together, I’ve now had the product for 8 months and had no issues wear/tear despite nearly daily use, but… it’s not comfy, at all. The seat cushion has a texture to it that scrapes at my legs if I don’t have an extra pillow on it or am wearing shorts. Additionally, the seat pillow is just kind of hard. It doesn’t give very much at all, so if I sit on it for more than an hour or two at a time my butt starts to get really sore. It works as a budget option, but invest in a good seat pillow if you plan to sit in it for any length of time.

A chair that does the job
Color: Black, Color: Black
I’m really happy with this chair overall. I wanted something comfortable, sturdy, breathable, and spacious enough for long hours at my desk when I work from home, and this chair delivered. I’d easily give this chair five stars because it exceeded my expectations in comfort, quality, and overall value.
Comfort and Support
The mesh back keeps it cool and comfortable during extended use. One of my favorite features is the adjustable lumbar support. You can manually position it exactly where your lower back needs support, and it fits the curve of my back perfectly. It provides great support without feeling too firm or uncomfortable.
Build Quality and Design
The chair itself feels solid and well-built. It doesn’t creak or make noise when shifting around, which makes it feel stable and high-quality. The seat is roomy and comfortable, and the overall design looks clean and modern.
Easy Assembly
It also came with an instruction manual that was extremely simple to follow, and assembly was very easy. I was able to put the chair together by myself in about 20 minutes without any help.
Armrest Functionality
I also like the armrests. They aren’t adjustable by height, but they do flip all the way up, which is surprisingly convenient. You can easily slide the chair under a desk or use it as an armless chair when needed.
Packaging and Presentation
Another thing worth mentioning is the packaging. Everything arrived extremely well-packed. Every individual part of the chair was wrapped securely, including bubble wrap protection for the components. The hardware and accessories were neatly organized, and the chair even came with the necessary tools for assembly in case you don’t own a drill or tool set. The presentation and packaging were excellent and showed real attention to detail.
Overall Impression
Overall, this is a fantastic office chair for the price: comfortable, supportive, sturdy, easy to assemble, and packaged exceptionally well. I’d absolutely recommend it and would confidently give it a five-star rating.

Nice chair
Easy to assemble and looks clean in my home office. The lumbar support is actually helpful, and I like that the arms flip up so I can tuck it under my desk. It’s comfortable for a full workday, though the seat could be a bit softer. Overall, solid value for the price.
