The RAM AIR SYSTEM is our flagship intake system that makes use of a conical filter with an inner and outer centre cone that helps accelerate ambient air, reducing turbulence. The carbon intake duct directs fresh ambient air to the filter and provides an excellent barrier from entering the intake stream. GruppeM's RAM AIR SYSTEM delivers constant and stable air flow throughout all driving speeds and acts to deliver maximum horsepower gains while maintaining increased torque at lower engine speeds. All GruppeM RAM AIR are made at our HQ in Japan. These systems are madeof the highest quality, hand-laid carbon fiber.
