the reason why we aren't all super happy and using the bmk-13 is because our mercedes all have the cartridge type filter , not the spin on. If anyone has a spin on, they should have installed the 13 kit already and should be smiling. I'm so annoyed my benz has the stupid cartridge filter.
Has anyone figured out the correct thread size for the oil sending unit fittings?
Most people tap the return line into the valve cover, sometimes oil cap, or down thru the oil drain plug(modified). Although the drain plug seems to be the easiest, i've heard from people with jetta bypass systems, and they've said the drain plugs can be unreliable. Doesn't matter how clean the oil is if its all on the pavement :-)
