Infinity Design Carbon Fibre Intake Kit – BMW 335i

INFINITY DESIGN was founded in 2014 operating from South Asia with the aim to provide the very best performance upgrades.
We design, engineer and build high end stainless steel and carbon fiber parts for performance cars.
We started with our world renowned S85 equal length headers which quickly gained popularity for it retaining the V10 sound track and adding serious power. This product has gone on to become the best there is.

PRE PREG CARBON FIBER DESIGN & MANUFACTURE
In 2017 we started our carbon fiber intake development using high end Artec 3D scanners, 3D CAD software, CFD analysis and 3D print technology for prototyping. By the end of 2022 Infinity Design has become a well known choice for the ultimate in air intake systems for a number of BMW models. IN HOUSE DESIGNED AIR FILTRATION
We designed and use our own in house developed ISO9001 large surface area dual cone filters. The goal was to deliver performance parts which not just performed on the dyno but in the real world also along with unrivalled build quality and sophisticated sound tracks.
Our development process is an immersive experience that engages the emotions and intellect as well as the senses to create world class products.

OEM Intake Analysis​
The factory intake system of the BMW M2 N55 system is not a sealed design. The front opening attaches directly the front inlet which is in turn attached to the front air ducts located behind the grills and there is a second opening which opens into the engine bay towards the headlight. This clearly suggests that one opening is not enough and the engineers had to create a separate opening to meet the high airflow demands of the engine which is understandable since the front intake has barely the same cross sectional area as the MAF. The design is still however efficient as far as keeping the intake air temperatures low. As far as being an ultimate performance intake, it is most certainly not with it’s angular design, small volume and having an airflow with a directional path which is not direct.

Our Design
For this application we have opted for large cross sectional turbo inlet tube with integrated MAF and a smooth non concentric expanding inlet tube which with silicone couplers. The expanding large volume inlet tube acts like a large velocity stack which accelerates the airflow and is much larger than the small and short velocity stack fitted to the internals of the oem intake. The result of the smoother airflow from our inlet tube is a far smoother lower rpm torque availability from the engine vastly improving drivability. Throttle response is immediately felt to be smoother and more eager.
The inlet tube is attached via a stainless steel v band clamp to the air filter housing which attaches directly to the oem front air feed and has a frontal opening facing towards the headlight.

Air Filtration
Within this beautifully shaped carbon shaped enclosure sits our bespoke short stack high surface area filter larger than any cone filter design currently on offer on the market with a huge opening of 170mm (6 3/4″) and is designed to take full advantage of the intake tube by altering the direction of the airflow towards the outer walls. By placing the air filter in front of the inlet tube we achieve the largest velocity stack ever seen for the N55 and which also has the best laminar flow. It is important to note that we have painstakingly opted for the largest possible air filter for a various number of reasons. Not only does a larger air filter allow for more air flow and therefore power but it also does not block up for longer and continues to be efficient at it’s main purpose which is to filter the air of harmful elements.

The air filter is completely encapsulated within the air filter housing rejecting the vast majority of the engine bay hot air and with the angle of the front inlet the air circulates around the air filter giving an even distribution of outside cool air.

Air Intake Temperatures | Heat Soak
The result is a system which matches the factory intake system for inlet temperatures. In addition the system changes the air flow characteristics for a smoother delivery and allows more air to enter the turbos more easily.

At just 20mph and above, inlet temperatures are equal to ambient under normal cruising conditions. Above 70mph even under hard acceleration inlet temperatures remain at ambient which ensures maximum performance without the ECU compensating by reducing ignition timing, altering boost and adjusting fueling as in hot air open intake systems.

This fully developed and intelligently designed intake system is not just something that looks good in the engine bay but does an impeccible job as an air smoothing device, increasing air available, increasing air speed into the turbo’s, allowing the turbo’s to spool faster, filters for longer more efficiently, keeps intake air temperatures low and making a sophisticated race car like intake noise under load. Most important of all, it is the way the engine becomes more alive, responsive and enjoyable to use not just under full load but also normal every day driving.
