Hey 8Club!

I was recently browsing online and came across this product. https://www.ebay.com/itm/11631750602...Bk9SR6be3drEZA I've always used oem filters but with how regularly I change my oil I feel this could potentially be a worthy investment. Plus I hate the idea of the millions (or billions let be real) of used oil filters buried in a landfill somewhere and like to think that this product offers a somewhat environmentally conscious option for those interested in such things.

Their claim is that it is a direct oem replacement for NR31-14-302 oil filter and think it would be great mod if compatible. I'm still waiting to hear about micron filtration but here's the response from my bypass rating inquiry. "Our filter has bypass differential pressure at about 14lbs. However our filter has extemely low oil resistance, so the bypass valve will not open basically, even at high engine revolutions in most engines. Also the diameter is 69mm, and the height is 82mm."

Think there's any merit to this filter? To my knowledge, it reminded me of https://seethroughfilter.com/ but in a basic 'no frills' type package. I get most owner enthusiasts will scoff at the price point but try to remember it's intended to be a lifetime filter.

Thanks for looking!

Probably a great product - but the ridiculous claims they make about what it will do is very off-putting!
Price is utterly ridiculous also!

Outlandish snake oil claims aside, every product does this to a certain extent.

For me, it's more of a "lower carbon footprint" kinda move as opposed to thinking about it in a monetary sense. It's something like 35 oem filters (at dealer cost = Asami filter cost) which is approx 5-6 years worth of stock depending on mileage, DE's, etc and definitely presents an argument to be made when factoring in the environmental waste. ymmv.

Thanks for commenting.

Asami filter rating is only 35 micron, which isn't the greatest imo. I came across this thread while digging for more info; post #103. Only 15 micron for oem high pressure sky active filter PE01-14-302 (which I speculate is similar in design to N3R1-14-302). Looking like it'll be contacting the dealer for an order soon.

First off, that seller is slapping a couple stickers on an aliexpress motorcycle filter and marking it up 500% Same filter on Ali Express for $65 with free shipping or
Second, all of the claims point to a much less efficient filter. Looking around online you can find other companies selling this exact filter with some of the marketing for this filter claiming that it filters to 35 micron. However, there's a lot of wiggle room on how a filters micron rating is determined that marketing can exploit. Without getting into the weeds on it, just because it caught 35 micron particles, doesn't mean it's catching a enough of them to be effective. There will be more particles that are big enough to cause bearing damage being left in the oil.
Here's a good quick article and a video testing a 35 micron stainless filter(the same rating as the aliexpress filter according to marketing) vs a 25 micron cellulose filter(typical for a good disposable filter.) Engine Labs test of Stainless media filter vs cellulose Short story is the cellulose filter was 85% efficient at removing the test particles(12-24 micron,) and the stainless filter was 17% efficient. Here's a video of the teardown of the engine used in that test showing the damage caused by the test particles not being filtered. We Put Iron Powder In Our Motor Oil... What Happened???

Also the filter media is glued in, which would make me a little nervous. While conventional disposable filter media is glued, it's exposed to oil for a short time (3-5k miles and/or <1 year) compared to a reusable filter. They adhesive in the reusable filter is also exposed to solvents used to clean the filter at every oil change.
This could be a non issue with proper material selection for the adhesive. However, with this being a chineseium product can you be certain they are using the correct adhesive or are they using the cheapest option they could find.

Not worth it.
