The oil hoses fit perfectly in front of the water radiator but you have to drill two holes in the radiator bracket to thread the hoses and come out of the air intake hole.
This is probably the easiest way to route the lines but at the cost of loosing the original air intake for the engine. Then again, it is not that bad sins you actually can shorten the air intake snout and thereby get cold fresh air in. The only "drawback" is that at full throttle you definitely can hear the engine breath with some snorkeling ruff sound. The first time I heard this sound I thought something was terribly wrong, but it is quite normal with the intake shortened and the air baffle removed from the air intake box itself.
