there are many different ways to go on air filters. i have never used an AFE and can not speak for or against it.
however, if you are looking for a SAFE alternative to the stock air filter to flow more air and still keep good filtration, i highly recommend giving a look at the amsoil EA series air filters. they are a drop in replacement and cost around $50. it is a dry filter than can be easily cleaned with low pressure air or a vacuum cleaner.
i have had one for over a year and it has worked flawlessly. with my TST and BD super B, i have never seen the filterminder move.
