Diaphragm of the actuator for changing the geometry of the intake manifold DISA for BMW with engines M43TU, M44 (as well as later versions of M42). Membrane diameter: 60.5mm

The diaphragm must be selected according to the original number of the Dis executive unit, since only the entire assembly is supplied in the original!

Original numbers of the DISA actuator:

11611438404

11611435715

11611247202

Note! There are 2 membranes installed in this DISA unit, we sell a large membrane.

Applicability:

BMW 3 'E36 (02 / 1993-08 / 2000)

BMW 3 'E46 sedan, Combi, Ci (04 / 1997-02 / 2002)

BMW 5 'E34 (05 / 1995-06 / 1996)

BMW Z3 E36 (12 / 1994-06 / 2002)

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 M43TU 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.
