The best way to add a port to monitor actual oil pressure, very useful beyond the stock yes/no oil pressure sensor.
This works great on most I6 BMW engines like the M50, M52, and M54, among many others!
It just screws into the standard oil pressure sensor threads, allows teh stock sensor to plug into the back, and a oil pressure sensor with 1/8 NPT threads to be installed into its side.
Truly the most clean way to get accurate oil pressure on these setups. For turbo oil feeds, we recomend the Vanos Turbo Oil Feed that we also sell, as it flows more fluid.
