The limited release model, the intake system birthed from the pursuit of even further enhanced inhalation efficiency and total performance.
How can heat, which has a huge influence on engine performance, be blocked? Exploring every potentiality, we persevered investigating every approach. Our aim however, would be to perfect a technique that would isolate the air intake passage from the engine compartment completely. That was our mission; this concept. Of course, there are the original (genuine) components, however, these components cannot reach “completeness” in terms of efficiency, because automobile manufacturers must make design concessions to meet cost criteria. In contrast however, Gruppe M pursues the ideal, without being subject to those constraints. Engineered to increase airflow, increase air velocity, stabilize the flow pattern, decrease intake air temperature, and decrease weight, the Gruppe M ram air intake system takes high-performance to a new level. Zero-tolerance manufacturing processes and expert craftsmanship, with efficiency being of the highest consideration, deliver intake systems worthy of the name “Air Intake Specialist”.
Design
To acquire power through the combustion engine process, it is not possible to avoid relation with air. The way in which higher oxygen content and cooler, clean air is readily supplied, is the important element for increased combustion efficiency. It is well understood that direct inhalation of air without passing through an air filter causes risk, dust and rubbish causing strain to the engine and related systems. However the filter itself may become an obstruction to air inhalation that diminishes combustion efficiency. Within the field of this dilemma, K&N has built a long history, from which comes the conception of the multilayer wet cotton fibre filter. By employing a conical filter shape, success in achieving both increased airflow velocity, and lower temperature is achieved. The restricted space in the engine compartment is used as effectively as possible through extensive design, and the route of the inhaled air is isolated nearly completely from the engine compartment by the intake duct made of carbon fibre. Moreover, the form of the intake duct has been calculated to exponentially raise the velocity of air by ram pressure. Not based solely upon the assiduity of a wealth of data, but due to repeated testing and trialing, an air intake not merely for form's sake, but of real demonstrated performance is accomplished.
Utilising the high density multilayer cotton of surpassing dust collecting capability made by K&N, of which there is no further need to tell you anymore about. The filter cases are designed to match each vehicle's character. Due to the heat blocking characteristics of the carbon fibre case, the influence of heat is successfully quelled, yet, due to the design configuration which boosts airflow velocity, stability is brought about by the rapid filling capacity, which in turn, further enhances efficacy.
It's all about craftsmanship... The air intake duct is lightweight, hand-finished carbon-fibre, creating a finished article that is lightweight, but moreover strong to take the forces of high pressure intake air, composed in the form of as gentle a curve as possible to best use limited space, and designed to minimise resistance to air inhalation. Depending on whether there is the presence of a supercharger or other such modifications, designs differ for identical car models and are made to the optimum shape. By means of ram air pressure, these air intake ducts, through enhanced airflow together with the chamber effect, even when operating at peak power, supply a surplus of air volume. Even in the feel of the material of carbon fibre there is no compromise; the workmanship in creating the finished product itself has adhered to making it a beautiful sight.
The Gruppe M intake kit fitting adapter is designed to fit all makes by means of a bolt-on design. Beautifully installed to fit flawlessly and neatly as an original component, the carbon fibre duct exudes an overwhelming presence. The kit includes all that's needed to install the Gruppe M RAM AIR SYSTEM, such as adapters and hoses. Each of the components are of the highest standard in order to deliver supreme performance.
* Installation is basically a bolt-on installation. According to the model, detaching the bumper may be required.
Genuine GruppeM RAM AIR SYSTEM has is mounted with an individual serial number plate, and management of each of these goods are by this unique serial number, and a guarantee of quality is given for six months. Please note that many copy articles have been appearing in recent years. Please be careful.
The K&N filter can be regenerated to as new condition with washing to give a wonderfully long life. The filter can be disassembled and washed to remove ingrained dirt without damaging the cotton. After washing and drying, by the application of filter oil, the filter is restored, showing 100% capability again. In addition, K&N air filters, not emitting undesired waste nor exhaust fumes on installation, clear test studies regarding regulations in every country in the world, so they can be used with peace of mind by even the most environmentally consciousness owner.
