Fenderwell - pulls cooler air from outside and removes filter from the hot engine bay. Cooler air = more condense, more compression, etc etc etc
But if you really want to know the best option...buy one from eBay for less than $40 shipped. Pretty much all of these products use the same filter, same type of tubing. A lot of the time you are paying for the brand name.
The filter REALLY doesn't do much in terms of power anyway, so why waste tons of money on a name.
I got mine off of eBay, no issues to date.
