Product: X8R DISA VALVE ALUMINIUM FLAP REPAIR KIT FOR M54 3.0L ENGINE COMPATIBLE WITH BMW E46 1999-ON 330Ci 330i 330xi DISA M54 3.0L PETROL ENGINE PART # X8R42
Brand: X8R
The cause: The original plastic Disa valve components wear and often snap causing the symptoms noted above. The pin retaining the flap can also pop out entering the engine! The likely cause of the faults noted above and most common cause is the weak plastic components within the DISA valve unit vibrating together and wearing causing the flap to operate at the wrong times and eventually leading to destruction of the flap plate. The pieces of this flap can even enter the engine often causing severe engine damage; likewise the metal pin that holds the flap plate in position can vibrate loose and enter the engine. The solution: Fit our improved design billet aluminium flap kit, designed to never fail, save the cost of a replacement DISA valve which will only fail again. Using our kit, the weak components of the DISA valve flap and crank lever are replaced with our many times stronger billet aluminium parts, retained by our precision machined screw, which tightly holds the two components together; eliminating wear and the need for the retaining pin which can enter the engine. Our part is completely redesigned to never fail- OEM clearances are reduced minimising vibrations in the part, preventing any future failure. Our kit also includes a high temperature Viton 75 O-ring to create a good seal between the DISA unit and the manifold, eliminating any air leaks.
