Review and Analysis

Upon analyzing the features and construction of both filters, it is clear that the Wix Oil Filter (51348) offers some advantages over the Microgard Oil Filter (MGL51348). The Wix filter has a sturdy build with a crimped metal seam and metal end caps that have minimal glue. On the other hand, the Microgard filter has a glued seam, excess glue on the metal end caps, and a slightly sloppier construction.

In terms of filtration performance, both filters claim to provide excellent protection. The Microgard filter boasts a cellulose media with a micron rating of 95% at 29 microns, while the Wix filter has enhanced cellulose media with a nominal micron rating of 21. However, the Wix filter offers a higher pleat count (62 pleats) compared to the Microgard filter (54 pleats), indicating potentially better filtration efficiency.

Another notable difference is the leaf spring type used in each filter. The Wix filter features a stamped leaf spring, which is different from the coil spring found in most filters. The significance of this difference is unclear, but it raises questions about the consistency of leaf spring types across different models.


After a thorough comparison, it is evident that the Wix Oil Filter (51348) outperforms the Microgard Oil Filter (MGL51348) in terms of construction, filtration efficiency, and overall value for money. The Wix filter’s solid build, enhanced cellulose media, and higher pleat count make it a more reliable choice for engine protection.
