The oil filter location on the R32 GTR is similiar yet worse than on a 90s Honda. On the 90s Honda they are on the underside of the block below the intake manifold, but at least you can reach it cleanly from the bottom of the car. On the GTR the front diff is in the way, and there is no way to remove the filter without getting oil the front diff case.

I decided on this oil change to move the filter location. I ordered a couple of adapters, some hose, and fittings.

I also removed the original factory boost solenoid and replace it with a MAC solenoid.
