There are lots of kits available for various applications, you'll have to fined out what the threading is. I personally find the stock location very easy to work with. Just life that flap on the side and your good to go with a oil-wrench cap thing.
its not hard to reach but it sucks when your constantly spilling oil from the filter all over.... I want to re-locate mine too.
I've read using a plastic grocery bag over the filter helps keep it clean. But I always forget when I'm actually changing the oil.
You know I just mean when taking the filter off....
