FRAM has been a top manufacturer of oil filters for more than 85 years, and we have studies, lab tests, road tests and various professional proof points regarding what intricacies of oil filter engineering, production and materials are most effective.

Bosch 3312 Premium FILTECH Oil Filter for Select Acura MDX, RL, TL, Buick, Dodge, Honda Accord, Civic, CR-V, Pilot, Hyundai Santa Fe, Isuzu, Kia, Mitsubishi, Subaru + More.

The Wix uses a much thicker coiled steel spring (look at the difference in thickness!) The Fram also uses a rubber anti-drainback valve which is more prone to brittleness than the silicone one in the Wix. The Wix on the left has 6 large openings, the Fram on the right has eight smaller ones.

The Fram is rated for 20 microns with 99% efficiency and will run as long as 15k. Since I usually run my oil 10-12k this filter is perfect for that. Used oil analysis shows the oil is clean and performing well for the mileage so I have no doubts this filter is doing a great job.
