Home > Variable Length Intake Manifold


Variable Length Intake Manifold (VLIM) is an automobile engine manifold technology. As the name implies, VLIM can vary the length of the intake tract of an engine in order to optimize power and torque. A tuned intake can have a light pressurizing effect similar to a low-pressure supercharger. This is due to Helmholtz Resonance .

Many automobile manufacturers use similar technology with different names. Another common term for this technology is Variable Resonance Induction System) (VRIS).
