I think it is just called an oil filter wrench, it will be metal and about 1.5" tall and have a 3/8 square hole on the end for the extension.
This one looks like it will grip the sides of the filter like a strap wrench does - OEM - "Cam Action" Import Car Oil Filter Wrench - Fits 2 1/2" to 3 1/8" Filters
This is the one I have used - OTC Tools OTC 6901 - GM Oil Filter Wrench
I just did a search for the images and don't particularly have either brand. The second one is size specific for the particular filter so if you have a couple different cars and want to use that style you would have to get a couple of different ones if the filter size is different.
One thing about the first change, you might want to have the dealer or quick lube shop do it. The filters can be a bear to get off from the factory, I had to mutilate the one on my 04 Ram to get it loose.
