Up on the workbench today is a Hengst H97W07, which Hengst lists as a cross for Toyota 90915-YZZN1. I am cutting a slew of filters to compare to the Wix WL10332 that I was thoroughly disappointed with for a variety of reasons, but primarily, poorly formed louvers.
The Hengst H97W07 is 2.89 in (73.5 mm) tall which taller than the Toyota 90915-YZZN1 and the Wix WL10332 by 1/4" on the Wix and 3/16" over the Toyota.
The can feels exceptionally well made, and the box is labeled MADE IN POLAND, Overall the filter weighs 231.0 g. Baseplate has 8 punched holes with no evidence of any burrs on the ADBV side, the baseplate weighed 96.5 g. Can thickness was the thickest I've measured so far and was found to be 0.0265 in thick. The ADBV is black but feels very pliable (possible not nitrile), not sure what material it is constructed from and Hengst's site gave no ADBV material information for this filter, it also lists the micron rating that I could find. The filter is constructed with The bypass valve located in the dome end, its setpoint is not advertised, and the valve is constructed of a 0.153 in thick semi rigid rubber disc sealing on metal with no visible light leaks. The BV opening is 7/16" in diameter. The filter core weighed 72.4 g, was 2 1/8 in tall, had 72 pleats, with a media length of 71 in, and a media thickness of 0.0215 in and used a metal crimped seam. The media is supported on each end by a metal end cap with no light leaks noted at the potting material, and no glue residue was present on the endcaps or elsewhere in the filter media. The center tube uses a formed and folded seam perforated tube with well formed holes that were all even with no burrs noted.
The only downsides I can fault this filter with would be the lack of published efficiency data, the lack of a silicon ADBV, and relative scarcity. I purchased this example from Rock Auto. Otherwise, it has by far the thickest can, heaviest base plate, most uniform construction, most pleats and filter media, and (in my opinion) the best BV design I've yet examined. Strong contender if you're in need of a filter for which this application fits!
