this may not work for you,but ihave an a1,,,,i removed the filter bracket,and welded 2 studs to the rad support,under the right side"frame rail",,and mounted it there,,you cant really see it from the top,,and ihave to lay on the ground to drain it, or put it on ramps,,its under that "rail",and i made a plastic shield up to protect it from front tire throwing debris,like big chunks of rubber from the tires smoking all the time,,its similar to the a2 splash shield setup in the right wheelwell,,imrunning a lift pumptoo,,so my setup without one may be hard to prime,,,but it does give more room in the engine bay

,sacrifice all in the name of speed!
