The Wix XP/Napa Plat beta ratios show a 50% @ 20 micron rating, but not much worse than the Honda OEM filters, which i believe are
If you take the efficiency out of the picture, the filter looks great upon every dissection and construction appears top notch.
I would be one of those to steer you into the Fram Ultra which is 99%+ @ 20 microns, and 80% @ 5 microns, the best posted figures of any company i have seen. Amsoil comes close with 98.7% @ 20 microns, but no 5 micron figure posted and price and availability are an issue.
