The DISA BMW unit (disa bmw) is used to change the geometry of the intake manifold (long - short) to improve the mixture formation in the cylinders and create a boost effect. The use of this unit on BMW engines allows you to reduce fuel consumption, as well as smoothly distribute the engine torque at different speeds.

Symptoms of a torn BMW DISA membrane:

increased fuel consumption

poor acceleration dynamics at low revs

intake manifold noise

errors on the poor mixture of the engine (air leaks)

as a result of air leaks - uneven idling

Over time, the membrane dubs and breaks, which disables the assembly. A new DISA BMW unit costs about $ 150. Our company offers the only correct solution - replacing the DISA membrane with a new one, which will restore the performance of the intake manifold geometry change unit.
