Product: 42508M + 42508MTS
Suitable for Alfa 164 with Twin Spark engine.
The set consists of 2 polyurethan-bushes for upper engine mount (passenger side on LHD cars).
Polyurethane (PU) bushes are about 30 % harder than OEM rubber bushes used which are used by the car industry. PU-bushes do not age while OEM rubber bushes get softer with the time.
PU-bushes can save a lot of money as they are cheaper than a complete new engein mount. Alfa Romeo does not sell those bushes as single items. The PU bushes may increase the audible engine sound in the interior.
