911URGE

Installed LN Engineering oil filter adapter, magnetic drain plug, Napa gold filter and oil change with Mobil1 0W-40 oil.

Old Porsche paper filter cut open and nothing but maybe 12-18 really, really small flecks of metal. Next up are motor mounts as my passenger exhaust tips are hanging a bit low. Looking to finally replace my PASM shocks, springs and LCA's later this spring since I already own them. Just never time or $ to get it done.

Did you test any of the tiny metal flecks with a magnet to see if they're ferrous material or non-ferrous material, like aluminum.

I have not but since you mentioned it I will do so in the morning as the filter is still on my workbench.

Can you tell us what are the advantages of using a spin on oil filter vs the original paper filter?

Does Mahle make a spin on oil filter for this application? I will probably upgrade to the LN kit, but the thought of a Napa oil filter in a Porsche just seems wrong.

Petza914

There are a multiple:

1. The biggest this is the spring for the bypass valve. When you use a spin on filter, you get a fresh spring for the built in bypass valve of the filter each time. When you reuse the OEM canister with a new filter insert over and over, you're reusing the same bypass valve spring. As springs age, they sag or don't sustain the same pressure as when they were new, so reusing that same spring can allow for some oil to always bypass the filter media and flow straight into the motor
2. You don't have a plastic housing holding the lifeblood of your engine. Plastic over time atrophies, especially if repeatedly heat-cycled, as the esters evaporate, weakening the structure of the plastic. The metal filter canister is both stronger and gets renewed each time
3. You can attach a filter magnet to it which helps to pull any ferrous debris from circulating through it

Read the oil filter tests. The Napa gold filters scores some of the highest marks for filtration and construction (actually made by Wix). Of course, you can always pay more for a Mahle, but it isn't any better.

I use the K&N ones myself as

1. I like the nut welded onto the bottom for ease of installation and removal,
2. it has thicker canister wall construction than the Napa/Wix,
3. has one of the thickest, if not the thickest square o-ring / sealing gasket on the top
4. uses a cellulose impregnated filter media to trap particles as low as 10 microns (many others are only spec'd to 15 microns)
5. has a silicone backflow valve that holds its shape and elasticity over the life of the filter better than those with a rubber backflow valve,
6. uses 8 larger diameter input flow holes in the top for increased flow through the filter, like at high RPMs. If the filter can't flow enough oil, it creates enough pressure to open the bypass valve and then unfiltered oil is being circulated through the motor
7. uses steel top and bottom end caps and center tube for durability
8. doesn't have a metal mesh on the inside of the filter media. If this mesh has any manufacturing issues, it's already on the inside of the filtering media and will go up into the oil pick-up. The filter companies that use this to reinforce their filtering media, should have put it on the outside of the media, not the inside as the oil flows into the filter from the outside, through the media, and up out the center to the motor.

Is this used for the 997.2 as well or only the 997.1?

Wayne Smith

The 997.2 resides at the top of the motor and is a completely different animal.

While Pete's explanation is excellent, as usual, one negative should be pointed out ... it is much easier to cut a paper element filter open for examination.

Seems like this thread for DIY modders would be a decent place to share a link to a cheap Numeric shifter for sale. $500 OBO, free shipping, no affiliation.

Correct. 997.1 only for the spin on filter adapter.

For the 997.2 and other DFI engines (like my Cayenne), ECS Tuning offers a very nice billet filter canister to at least eliminate the plastic failure point, but it doesn't help you with the spring and bypass issue as you have to move the spring from your current canister over to it.




For cutting open metal filters, you need an oil filter Cutter, like this. Doing it with a saw will contaminate the media and you won't know what came from the engine or from the cutting process.

I found that for my 997.2, I can buy the entire oil filter cartridge, o-ring and the plastic cap pre-assembled from porsche for a couple dollars more than just the cartridge and o-ring.

I've almost started a thread for good deals on Porsche parts, accessories, etc multiple times. Good deal!

Sold it due to IMS bearing failure :-(
