Variable Intake Manifold - An automobile internal combustion engine manifold technology. As the name implies, VLIM/VIM/VIS can vary the length of the intake tract - in order to optimize power and torque across the range of engine speed operation, as well as help provide better fuel efficiency. This effect is often achieved by having two separate intake ports, each controlled by a valve, that open two different manifolds - one with a short path that operates at full engine load, and another with a significantly longer path that operates at lower load.
Ventilated Rotor - Reduces the heat created with braking, where the brake pedal presses against the rotor, causing friction.
VIN - VIN or Vehicle Identification Number - is a series of 17 alphanumeric characters that uniquely identifies your vehicle. The characters themselves record specific information regarding the vehicle manufacturer, place of assembly, and other pertinent information.
Voltmeter - An instrument used for measuring electrical potential difference between two points in an electric circuit.
VTEC - Variable Valve Timing and Lift Electronic Control. Improves the volumetric efficiency of a four-stroke internal combustion engine and allows the engine to have two camshafts.
