• Ram-air intake systems are designed to : get more air, and thus more fuel-air mixture, into an internal combustion engine. They represent intermediate steps between a standard naturally aspirated engine and a forced induction system, such as a turbocharger or a supercharger. Provide more performance than a conventional intake with a minimum of additional complexity. So its a way to get more in without the external parts like a turbo or like in the Kawasaki Ninja H2 a supercharger. Its even in cars The classic ram-air intake is that seen on the Formula Firebird, which consists of one or more forward facing scoops that are designed to force, or ram, more air into the intake manifold.. In many ways, this system is almost a hybrid between natural aspiration and forced induction as it compresses the air before it reaches the manifold. When tuned correctly, this option can provide a significant power increase. The biggest drawback to this system is that because it relies on the vehicle's forward motion, it is only really effective at speeds of 40 miles per hour and above. At lower speeds, it loses most of its effectiveness as the air does not reach the scoop quickly enough to be compressed. They first appeared on production motorcycles on the Kawasaki Ninja ZX-11 model in 1990.
