This RAM air intake design also takes advantage of the cooler air outside the engine compartment. Cooler air is denser, and denser air in your intake allows more oxygen to your engine. More oxygen means you can burn the same amount of fuel more efficiently.
With greater mass airflow and lower I. A. T provided by C.A.I systems, one can expect greater horsepower and torque through the power band with a more direct and responsive feel upon pressing the throttle. Sounds from the engine and turbocharger are enhanced and some may even experience better fuel economy depending on driving style.
At German Auto Service & Repairs we use APR and Racingline C.A.I products because we realise to increase performance over the factory intake system, the intake system’s ability to flow a higher mass of air is critical. Both brands offer multiple systems for a wide range of V.A.G models and provide the highest quality products on the market as they spare no expenses during the research and development period.
In order to maximise performance, APR’s and Racingline’s Mechanical Engineers focused on improving the pressure ratio between the inlet and outlet of the intake system, reducing turbulence, maximizing filter efficiency and keeping I.A.T as low as possible. When developing new C.A.I products, their Mechanical Engineer’s spend the better part of a year creating several prototype intake designs utilising their in house Sterolithography 3D printer and other rapid prototyping techniques.
Various filter mediums are tested in conjunction with the new intake designs through simulated CFD models, flow bench analysis, dyno data collection and in real world applications to achieve the best possible solution
