Recently installed e36 m3 inline filter on my 2008 dct e92 m3.
Have done 4-5 tanks now with some spirited backroad driving and with some high rpm winter fun.

Have not yet checked the fuel pressure or condition of spark plugs but overall cant see, feel or hear anything different - will update in few months when the weather is warm and track is dry.

As the filter is located before the fuel pressure sensor i doubt that there are any issues. Seems like the Chinese market e9x m3 has same kind of filter in same location.

Also was not feeling confident about installing fuel filter right above the veeery hot exhaust manifolds.

In total ~5cm of the original fuel line was cut off so that the original fuel line holder brackets can still be used. Also after cutting the line its not hard to clean lines from debris - can access the line from engine side and from tank side can just turn the ignition on and fuel pump blows the remaining debris out. Also flanged the fuel lines - that required hydraulic flange tool .. PITA.

Made simple aluminium bracket - didnt want to cut holes into the cars frame so used the original underside panel holder hole for one side (underside panel didnt have hole for it) and other is just aluminium sheet turned into U shape, added some rubber protection for the aluminium bracket and also fuel filter so there will be no metal to metal contact. The filter is fixed and super solid - no movement at all and with underside panel on cant see anything.

Todo: 3d printed bracket for fuel filter, replace rubber fuel line with braided and use AN fittings? or something more solid - nothing leaking but before going to track just want to be sure.
- does anyone have picture from underside of the Chinese markets car? There is probably part number for the original bracket

Sorry for ugly pics - car is extensively covered and filled with Dinitrol ML.
