PX600 Pipercross Airfilter System for Alfa Romeo Nord Engines
This is the Pipercross PX600 air filter system for 1 Alfa Romeo Nord engine with 2 twin-choke Weber DCOE, Dellorto DHLA, Solex DDH or Solex ADDHE carburettors.
Fits the 40, 45 and 48 mm versions of these carburettors.
An explanation of this ingenious system can be found HERE and the PX600 is basically the "double" system from the PX300.
The filter element is 435mm long, 190mm wide en 120 mm high (please also see the dimensions in the photograph).
Please note that in order to use this system, you need to remove the original cast aluminum air filter housing.
Should you want to attach the original carburettor support, it would require drilling 2 holes to attach it to this backplate.
The plate itself offers enough stability to maintain synchronization between the front and rear carburettor.
The complete set consists of backing plate C6131 and filter element C603D.
