What You'll Learn

Carquest fuel filter quality
Carquest fuel filters are manufactured by WIX, a reputable company that also produces filters for other brands such as NAPA. Carquest offers two lines of fuel filters: a premium line and a cheaper line.
The premium line is the one in the blue box, which is manufactured by WIX and considered to be of good quality. The premium filters are well-constructed and appear to be well-made, with some users commenting that they are happy with their purchase. Carquest premium filters are comparable to other name-brand filters in terms of quality and performance.
On the other hand, the cheaper line of Carquest fuel filters is the one in the red box. This line is not manufactured by WIX, and there are concerns about the quality and origin of these filters. Some users have expressed that they would not recommend using the cheaper line of Carquest filters.
In terms of filtration efficiency, the premium Carquest filters are rated at 99%@25 microns for the Premium Guard "Selects" and 93%@25 microns for the standard line. These ratings indicate that the filters are capable of capturing a high percentage of particles larger than 25 microns, which is important for maintaining engine health.
Some users have noticed changes in the Carquest filters over time, including differences in faceplates and suppliers. It appears that Carquest has switched suppliers multiple times, and there are concerns about whether the current filters are still made by Purolator. Despite these changes, many users continue to trust the quality and performance of Carquest fuel filters, particularly the premium line manufactured by WIX.

Carquest filter alternatives
Carquest oil filters are manufactured by Mann+Hummel, a German company that has been in the business of manufacturing oil filters for various types of engines since 1941.

Other alternatives include K&N, Fram, and Bosch, which are all known for their high-quality oil filters. These filters can be easily found at most auto parts stores or online retailers.

Lastly, for Audi-specific alternatives, Mann, Mahle, Knecht, Hengst, and Mobil 1 are recommended by a user, with Mann filters being OEM equipment for VW/Audi.
