M54 M52tu oil pump faceplate upgrade

Now you can upgrade you oil pump by replacing the faceplate! This upgrade allows you to replace the standard faceplate so that a guide rail can put pressure onto the oil pump chain, helping to eliminate chain whip!
This product is the supply of just the face plate and the guide rail with all required fasteners! 
It will work with the OEM pump shaft but is also useable with other aftermarket shafts, of course we recommend using our 4 bolt shaft for ultimate security!
