Most cold-air intake systems come in four main pieces. There are two mandrel-bent aluminum pipings, one billet-aluminum MAF adaptor and one high-flow filter. Par for the course--results tend to add from 3 to 5 horsepower.
The frequency of the sound wave generated by an intake system varies with it's length--longer systems tend to generate lower frequency waves. With traditional cold air intakes, as the RPM increases, inlet valve opening increases while the inlet tract length remains constant. Over a period of time, the increasing frequency of the inlet valve and the inlet system resonance become out of phase with each other and the effect of using sound pressure to promote cylinder filling declines.Get a ebay CAI they all do the same thing some are just shiner then other
