I Am Speechles
K&N® - Fuel Filter
I never had replaced my fuel filter at all on my 05 Ford Focus. My old one was pretty bad shape (obviously). I felt the difference once this filter was installed. My acceleration was better as well as my fuel was lasting longer. I do plan on buying this one every year no matter what car or truck I will have by then. Highly recommend this item and K&N brand and their products.
