Searched the forum for cross referenced oil filters, didn't find anything, so I did some research digging. Here's what I found: I've found a lot of filters that will cross, but here's the most popular. Keep in Mind, WIX makes Napa brand filters. So the numbers are almost the same. Donaldson and...
Depending on how hard you drive and the weather, follow the manufactures recommendations. Use high quality oil. There are a set of digital download service and owners manuals for the Roxor. Download those as soon as you can. They are the complete factory repair guides.
The Napa website lists Wix (part 51324) as the manufactuter of the Napa 1324.
I have wondered for some time about oil filter bypass valve specs. There were some early posts on this board about the bypass valve. I spent some time researching if above oil filters would be the a good fit.
A website says the Roxor has the m2dicr engine. Pictures of the Bolero show the same engine (m2dicr, 2523 cubic centimeter displacement). The specs for a Bolero oil filter show a 1 bar (14 psi) bypass valve.The Wix 51324 / Napa 1324 have a 16 psi bypass valve. Looks like a good fit.
See I for one want to run a dual Bypass kit on mine Rox. Once I find the right adaptors I want to run my oil through the full flow 20micron filter as well as the bypass filter that filters too 2 micron. I'm an Amsoil guy and would love to only change my oil when the oil sample says so when I send off to lab. Great way to see the internal workings of the engine. I have the kit just need to find the right adaptor for the engine. Once I get the right adaptor for the engine I can run Amsoil filters as the full flow and bypass filter.
I have this kit just need to figure out the adapter for the oil filter and I'll be golden. Those wix filters if you can cross-reference what all applications it will fit on I'll be able to figure out the adapter. Since we don't know what Amsoil filter it takes it hard to determine the adapter https://www.amsoil.com/p/universal-dual-remote-bypass-system-bmk23/
@mickeybobs: I agree. I will use the 51324 for the next oil change. 0.5" taller than stock probably means more filter surface (since I have not cut open a stock or 51324, I don't know if that is true).
