Anyone use an aftermarket oil filter insert lately?


For the first time, I bought a Mahle (part # OX-128/1D )oil filter insert from an online parts retailer, and it did not fit.


The height is the same, but opening is too narrow (see photo) , so it doesn't fit properly inside the oil filter housing.


I made multiple trips to two different local parts stores and tried, with no success, Framm, Mann and Hastings (and a couple of others) that were listed as the correct part but they had the same issue as Mahle. The Porsche number is 996-107-225-53 and both parts stores told me the Mahle part is listed as the correct filter insert (as were the others that didn't fit). In fact, the Porsche OEM filter that I removed also has this same number (OX...) stamped on it.


Anyone have part number for an aftermarket oil filter insert that works (all years of 996's and all engines use the same oil filter insert)?

 

It 'appears' to be correct. When I first changed my filter years ago, I thought the opening of the new part was too narrow. Eventually, I figured out that the neck expands once inserted.

Mahle, btw, is a supplier of Porsche.

I am wondering why you went aftermarket. Just shop from one of the sponsors here like Pelicanparts, suncoast, etc.

I got the Mahle filter from Pelican and yes, I knew they are an OEM supplier. It was $10 vs. $32 for the Porsche one, and I thought they were identical -- but apparently not.


I'll try pushing the Mahle one into the filter housing and see what happens. Thanks for that tip.

 

Eureka! I gave the Mahle filter insert a firm push, and it went in with a solid snap. Now it sits nice and flush like the OEM one. I was able to easily pull it out of the housing with my finger, so there's no chance of it getting stuck in there forever.


Many thanks!

 

Congrats!

Now cut up that paper filter and expand it to check for any debris. Most likely, it would be debris free.

 

How do you cut up the filter? The paper part seems to be attached to a plastic frame on the inside. Do you cut a slit from top to bottom and then peel off the paper from the plastic frame?


BTW, last time I changed my oil (about 2 years and 600, yes 600, miles ago), I sent the oil to Blackstone Labs for analysis and they found everything to be just fine.

 

Checking the he paper filter is optional. Obviously, you can check just by spreading the folds with your finger. Me? I just enjoy cutting it up and spreading it wide.


I just use a box cutter, lay the filter on its side (hirozontally), cut the top and bottom parts (the disc hats), and that's it.

 

Ordered a OEM oil filter from some online parts supplier for my 2008 Cayman S. I happened to have a factory filter, one I had bought at a dealer parts department. The two filters did not look to be the same. I tossed the filter I ordered/bought online and used the factory filter, the one I bought at the dealer. That was my only experience in using an aftermarket oil filter in my Porsches. Before that one time and ever since my filters come across the Porsche dealer parts department counter. With my PCA membership I get a discount and the cost is close enough that the difference is not significant. And the peace of mind knowing the filter fits properly and is the right filter is priceless.

 

Just realized that I have been using Mahle for the last 50,000 miles. I buy the filter when my order is almost at the "free shipping" threshold.

 

Mahle and Mann are both excellent filters..Suppliers like Pelican and other usually have both.

 

Mann also makes a fitment.

 

Have you considered the LN Engineering Spin-On adapter? It allows you to use conventional oil filters and the "experts" generally agree that they actually filter out far more impurities than the stock filters because there is no bypassing of the filter.

I've had one for about 4 years.

 

This is one of the best mods you can do IMO, I've had one for over three years and couldn't be happier.

 

Im banking on the Porsche engineers passed Filter Technology 101 in college,,my father in law has a newer MBZ CL500 and it has a filter cartridge, only 2 of them,2batteries also, one for electronics, one for engine.. Im glad to be driving a simple car

 

So when you buy a replacement spin on filter, which vehicle do you specify that it is for?
