I haven't seen much about these written or discussed. While I was at my local CrankyTred aka CanadianTire I looked into these and brought one home. The numbers are mostly Fram based but have a twist. MOPH****: is used for the can filters, basically MoFram! MOCH****: is used for the cartridge filters. It can make things fun when searching. The selection covers the popular filters right now, so they don't cover the full range. I wanted a 4386, but they only have the 3614 as the closest equivalent. I looked at the PH3600 and PH2870a, and the base plates and cans were identical. The 3614 was shorter obviously. The base plates had a a pattern I hadn't seen before, 8 relatively large, holes with a 'AA' stamped in it and the hole edges are burr free. It's a louvered tube, and all three filters I looked at were clean and open. The silicone ADBV is quite substantial looking but probably blocks 30-40% of each hole. The grip end has concave grip surfaces, 15 of them along the top, much easier to grip than flats. The specs CT gives are generic but here they be: - Up to 99% Efficiency - 16,000 KM lifespan - Meet or exceed the OEM specs - Durable steel shell, painted matte black. - Synthetic blend filter media. - Silicone anti-drainback valve. - High strength steel base plate. - Synthetic and conventional oil type compatible. - Premium oil filter type. - Made in the USA I don't really recognize the filter, or I'd add some of those lovely specifications like actual efficiency, flow, bypass, etc. I picked up a MOPH2870A the size specifications are... weird... Height: 2.75"(6.99cm) Depth: 1.35"(3.63cm) Width: 2.75"(6.99cm) The width is uhh... hmm... the box is square on the end and rectangular on the side, so tall and skinny not... I'll measure in a bit. Pictures: I apologize for the potato quality of my phone camera... Hope this helps demystify this Canada only variant a bit. Hopefully the media and the bypass is good... I really do need to get myself a filter cutter one of these days.
