The way this oil cooler kit adapted to the OEM N54 oil filter housing and OEM oil cooler assembly was nice. Machined adapter to adapt the housing to AN fittings.
Kind of shows how the oil is routed. IIRC oil pumps out of the driver's side port and returns via the passenger side port. You can see the stupid coolant line is all kinked because of the aforementioned genius moment.
Ziptied the crossover line in place. Just there to keep the hose from flopping around between the subframe and the bellypan.
The passenger side of this kit fit amazingly, as it reused the OEM mounting brackets. The drivers side was a piece of shit compared to all of the other OEM-like components I had already installed. I coerced it into place but I'm not happy about it.
With the fan in place you can see the AN lines if you're looking and the VRSF chargepipe coupler peeks out also.
Filled it up with liquimoly and crossed my fingers. No leaks on startup and first heat cycle.
