Spin-Oil Filter or conventional?
 

LN Spin-on or Porsche daisy cup?

LN Spin on w/ NAPA Gold filter.

LN spin-on. I did an extensive search of the net and those that wrench on these cars and know what they are talking about all recommended the spin-on.

And, I use a Mobil One filter because.... because.... ahhhhh.... because it cost the most so it must be the best. Yeah, that's it!

For me, LN spin-on with Wix 51042

I just became aware of another billet filter, Canton makes a 13/16 thread 3.4" tall billet filter (same height I think as the 51042)

Filters down to 8 microns, no bypass, and 12 GPM (21 microns and 9-11 GPM for the wix)

Downside is expensive inner media costs, but the inner media has a longer life, can can open the oil filter to inspect for bigger particles and then put it back together, changing out the element only when you get to the desired mileage.

If the Wix gets closer to the 9 GPM (in the 9-11 range they give) I wonder if that extra flow would be useful. Or is it just another way to spend extra money :)

I am about to install the LN Spin On Adapter, it's pricey, but I was impressed with the craftsmanship. Went with the Wix 51042XP. I couldn't bring myself to spend $50 on a FilterMag, so I taped some old hard drive magnets to the filter.

have you cut open any filters yet?

I haven't installed it yet, planning on this weekend. I'll try to remember to report back in 5,000 miles.

Please do, you might be the only person experimenting with the magnetic element on the forum.
I'm surprised this hasn't been discussed more. Sounds very logical. A system with 100% filtered oil and elimination of nearly all the ferrous material large enough to get caught seems like a major improvement over paper filter which provides neither.

We have a lot of customers running the LN adaptor with the Wix XP filters, and a fair number also running the FilterMag as well. Several of them have been startled by what they found after their first oil change as the FilterMag tends to clean out all the fine ferrous grit that has been circulating through their old filter set up.

The factory filter housing has a bypass that can easily send stored debris in the bottom of the container, around the filter and into the primary oil system,

The design of this bypass is less than optimum.

Sounds like Spin-On with filtermag is the way to go for a high mileage car.
Now that I've crossed 100K this seems like the right move if not overdue.

I'm about 1000 miles away from my first oil change running LN, Spin-on and filtermag. Didn't mention the filtermag on first post. I will post results and pictures if possible.

I have just done an oil change and fitted a LN spin on adapter with a LN billet housing and 60 micron washable filter. I will report back on my next change but that will be a while still.

So far, so good.

can you post which Wix and Filtermag you used? The link on the LN site indicating which Filtermag to use is not working. This would be helpful for those searching this forum.

Sure Perfectlap! I am running the NAPA Gold filter 1042 which is basically a rebranded WIX 51042. The Filtermag is the SS300 for 2.9 to 3.4" diameter filters.

OEM + magnets on the housing (DIY). ;)

I may machine my own adapter in the engineering depatment this fall. The LN tax is too high for me to justify.

Thanks! Do you have the FilterMags in there as pair or just one?

pictures or did not happen...

What sort of magnets are you using? I see there are really strong ones in the market, seems like you want those that can pull the tiniest micron through housing+oil and account for fluid motion.
