For 31 years GruppeM has created innovative designs that help push intake technology beyond the accepted norm. Our Ram Air System utilize the highest quality hand-laid carbon fiber are individually crafted by our experienced artisans, and tested in-house by our veteran R&D team. We use CAD & 3D printing to ensure quality is maintained throughout the design process. Our precision RAM AIR SYSTEM are designed to be a fully functional integrated component in every application. Our endless commitment to intransigency has led us to create arguably, the best intake systems in the world.

The RAM Air Intake System, commonly known as Cold Air Intake (CAI) is our flagship intake system that makes conical filter, with an inner and outer centre cone that helps accelerate ambient air, while reducing turbulence. The carbon intake ducts directs a fresh, cool ambient air to the filter and provides and excellent barrier against heated air from entering the intake stream. GruppeM's RAM AIR SYSTEMS delivers constant and stable air flow throughout the entire RPM range delivering maximum horsepower gains while maintaining increased torque at lower engine speeds.

Our RAM AIR SYSTEM designs work by reducing the intake air velocity by increasing the cross-sectional area of the intake ducting. When gas velocity goes down the dynamic pressure is reduced, while the static pressure is increased. The increased static pressure in the plenum chamber has a positive effect on engine power, both because of the pressure itself and the increased air density that this higher pressure gives thereby increasing engine performance and output.
