What is the best fuel filter for this car?
Any specific application you are looking for the best for? Any reputable one works be it OE, OEM+, or JDM aftermarket if you are a purist. No need to get the very best otherwise.

No I just wanted to make sure that in a week I don't need to buy another fuel filter, and was hoping I could get something cheaper.
Your fuel filter getting dirty after a week, shows that you have a problem that is not due to the filter. Replacing it is a temporary solution then. Find the issue as to why it's getting dirty so quickly, then you can replace the filter. I would not cheap out on a good fuel filter, just like fram oil filters, the cheaper you go it's gonna be just flimsy paper ones...
I would just go OEM.
