Performance Gain: 8-12hp, 8-10ft-lb
The BMW E39 M5 Eventuri intake is designed to offer a complete solution as an upgrade to the stock airbox system. Their aim was to develop an intake system for the S62 engine which worked with the stock ECU map and MAF sensors and produced a genuine improvement in the driving experience. With the Patent Pending Venturi housing, they have ensured that the airflow remains as laminar as possible. Furthermore, the addition of a true cold air feed by adding scoops integrated with the front fog lamps results in the lowest possible inlet air temperature. This leads to an optimised intake system which delivers noticeable performance gains consistently.
The Eventuri Difference
The E39 M5 Eventuri system uses Eventuri's Patent Pending Carbon fibre Housings with a bespoke Gen-2 filter which provide an aerodynamically efficient airflow path from the filter to the inlet tubes. Not just another cone filter with a heat shield but a unique design which invokes the Venturi affect.
PERFORMANCE
The standard airbox draws in air from behind the front bumper so the flow path is long and this introduces drag in the system. Furthermore the cuboid nature of the airboxes give rise to turbulence where the transition to the circular MAF tubes take place. Our system replaces the airboxes with Venturi housings which transition much more efficiently to the circular MAF tubes maintaining laminar flow. The filters draw air from a shielded part of the engine bay which is saturated with cold air from the integrated foglamp scoops. By keeping inlet temperatures low and improving the flow path efficiency, the engine is able to produce more power. The dyno graph below shows the comparison between the stock airbox and the Eventuri intake system on a standard car with standard map and exhaust. Dyno runs were done back to back on the same day and with the hood closed.
PRODUCT DETAILS
The Eventuri E39 M5 intake system consists of a number of components engineered to perform a specific purpose and fabricated to the highest of standards. Here are the details for each component and the design ethos behind them:
Each intake system consists of:
- 2 Carbon Fibre Venturi housings
- 2 High Flow generation 2 Air Filters
- 2 Aluminium Cowls for smooth airflow entry
- 2 Foglamp surrounds with integrated air ducts
- 2 Flexible Neoprene air ducting sections
- 2 Laser Cut Aluminium Shields
- Laser Cut Custom Brackets
- High quality Silicon couplers with BMW specification hose clamps
Carbon Intake Housing Assemblies
The filter housings comprise of the high flow filters, aluminium cowls and the carbon pods themselves. The carbon pods shroud the reverse mounted filter and smoothly shape the airflow down to the MAF tubes. This smooth reduction in cross sectional area invokes the Venturi effect where the airflow accelerates whilst maintaining laminar conditions. It can be thought of as a large velocity stack - below is a diagram to show the comparison between our patent pending design and a regular intake system. Our bespoke filters aid the airflow moving through the housings and allow for an even velocity profile as the airflow exits the housings.
Foglamp Ducts
To supply the intakes with cold air we designed replacement Foglamp surrounds with integrated ducts. The area for cold air entry has been maximised for the given shape and size of the surround and the duct transitions to the supplied flexible neoprene ducting tubes. While the car is in motion, ambient air is forced into these ducts which are connected to the neoprene tubes to transfer the airflow directly to the intakes. This ensures that the intakes do not get heat soaked and the engine is able to draw air at ambient temperatures.

Comfort and ease
Color: Black, Style: With Headrest
Good chair all the functions work well I don’t really care for the armrest rotating but the fact they lift up an extend is nice. It’s comfortable. The lumbar is good. I don’t spend hours in a chair. It’s nothing fancy but definitely good for the price. Simple to put together seems durable enough.

Good chair but....
Color: White, Style: With Headrest
I am 20 years old and a college student, I have horrible posture, and I game a lot, so my chair is VERY important to me. This chair was decently okay to assemble, and the initial sitting experience is good. You can feel yourself sink into the seat but not too much which is really nice. The arm rests are tiltable which is AMAZING because I always have a weird stance when I sit so this is perfect for me. However, there is one thing about this chair that is CRITICAL to know before buying. Perhaps this is my own fault, but the back isn't adjustable. What I mean by that is that you can't lean the back of the chair forward, kind of like how you can in a car seat. There is a pillow that you can push further into the back rest with a nob on the back but that barely helps. The headrest is also abysmal because I have to lean so far back into the chair just for my head to hit the head rest. I want a headrest that is always against my head. Not something that I have to tilt my head back into just for my head to hit it. That makes the chair extremely uncomfortable if I am trying to use the headrest. The chair also feels wobbly, I have had previous chairs where over time the gas lift wears out over time and when I sit on the chair the chair falls to the ground because the gas lift doesn't work anymore. However, that takes years of wear and tear. Sitting in this chair makes me feel like it is going to happen way sooner. Also, the picture makes it look way whiter than it is in real life. It is kind of like a white that is getting to a pee color and it is kind of gross looking a little bit but it isn't that bad since it isn't fully that color. Another thing is that crumbs actually get stuck in the tiny holes in the seat cushion so you can't swipe it off your chair they are literally inside of it. I will leave a better review once I had used it for a while. If you are just looking for a nice chair and don't really care to much about the specifics it isn't a bad choice.

Good quality and good price
Color: White, Style: With Headrest, Color: White, Style: With Headrest
Very easy to assemble, comfortable, sleek design, and the colours are just as pictured. I can't speak on durability as I just got it. The back support works well. Something I loved is that the head and arms support adjust to your needs.

Would Buy Again!
Color: Black, Style: With Headrest, Color: Black, Style: With Headrest
Purchased this chair several months ago and very pleased with the quality, durability, lumbar support, head rest, rollers and multiple adjustment. I use it some 8 hours a day, it's very comfortable, and highly recommend. Thus far great product for the value.
