It looks good, but as usual the devil is in the details. I looked at the site and could not find any info on how well the filter performs...just the marketing crap from the above link.
There are two SAE tests that will give you an idea how well a filter performs:
SAE J806 - Tests the filter contaminant holding capacity, size of contaminant particles trapped, and ability to maintain clean oil.
SAE J1858 - Tests both particle counting and gravimetric measurement to measure filter capacity and efficiency. For example 40% at 10 microns, 60% at 20 microns, 93% at 30 microns, and 97% at 40 microns.
This filter has a silicone anti-drainback valve...a plus. The by-pass valve appears to be coil spring steel...also a plus, but is located at the top of the filter. That's ok, but if the filter goes into by-pass, oil will be flowed over a dirty filter element. The Wix has the by-pass located at the oil flow entrance.
Media wise, they make no mention of the material used. It would be good to know the surface area of the media and the number of pleats. No mention of flow rates either. I'm wondering why they are using a metal mesh to support the media on both sides. Unless it's a material that is easily collapsed, it should not be necessary.
The magnet is a good one too (more marketing hype)...it is very small. It will catch metal particles, but is located in the center of the media...the oil has already passed through the media to come in contact with it. If the filter is doing its job, there should be very few particles (as in none) left. If you want to use magnets, get neodymium magnets out of an old inop hard drive and stick them to the outside of the filter.
Another thing to consider is the metal casing...if you are running a high pressure oil system, this is very important. Unless you are willing to risk bursting the filter
The filter JJ mentioned (Amsoil EAO) is probably the best spin-on filter available...it's expensive...as are filters like the Canton. If you really want to remove particles below 10 microns, use a by-pass filter in conjunction with a conventional spin-on.
Personally, I use a Wix filter. Hard to beat it (or the PureOne) for the price.
The Denso-Japan filters Jeff provided the part numbers for are quite good...the Toyota filters made in Thailand are average at best.
