LN engineering filter adapter
 

okay so here is bit of a twisted question...

why add the adapter to use a spin-on steel filter? is the cartridge unit that porsche chose for the 986/987/996/997, provide poorer filtering when compared the units that would fit on the adapter?

I'll let Charles chime in on this one, but he doesn't terribly care for the cartridge-type filters, and thinks there are better filters available in the aftermarket. I sent him a note regarding this thread...

Good question! There are mutiple reasons to use the spin on oil filter adapter.

The original reason to make the spin-on oil filter adapter was to allow us to use readily available adapters to easily plumb in an external oil cooler or Accusump. Everything else was just secondary, but we've found that many people like them because it just makes oil changes easier.

The original housing is just cheap and so are the filters. You wouldn't believe the number of thank yous we have gotten since releasing this product.

We realized was that the OE filter wasn't that great and that by allowing use of a more common 13/16-16 filter thread, we had many filter choices that were both easy to find at any auto parts stores and in most cases, significantly cheaper too even when upgrading to Mobil 1 or K&N Gold branded filters which far outperform the OE filter with respect to the quality of filtration provided.

Long story short, the Mobil 1 and K&N Gold filters are a well constructed filter, using synthetic resin impregnated filter media capable of filtering lower micron particles while not restricting oil flow. There are many oil filter studies out there and they all come to the same conclusion that these filters are the best.

With a steel bodied oil filter, you can also use a Filtermag, which we've determined products like these do work to nearly eliminate iron particles from the oil, which those particles are a primary source of wear.

The most common question I get is why we didn't make this use a Porsche spin-on filter. While we could do this, it would defeat the purpose. The only filter properly sized is the secondary 993 filter, and really the only people who keep those around are dealerships. Shops using our filter adapters can purchase through local parts houses the M1 or K&N filters, or even the Napa Gold filters we also recommend in bulk master packs for next to nothing.

The next common question is how did we come about the filters we have chosen? Napa Gold 1042, M1-107, or HP-1007. They are full flow without a bypass, like the factory configuration. They are similarly sized and provide similar ground clearance. However, there are many more that could work too.

My filter adapter is sitting in the box waiting for install once the weather breaks (springtime). I'll be purchasing the new filter and draining the Mobil 1 I just put in last fall...after the comments on Mobil 1's formulation, I don't want to risk any problems even though I change it about every 2500 miles (once a year).

Thanks Charles (and Jake) for your expertise on the M96 motors; with just 15k miles on mine, I hope it lasts many more years.

thanks
 

thanks for the reply, i will look at this update later this year, up here in the frozen north, access to such items as mobil1 filters is very limited or non existent (small centre far from the American border), so i will need to check for a source
