Oil Filter PN Question

So I was going to buy a filter for my '17 M2 to do an oil change, and I noticed that the PN was different than for my '11 335, which sort of caught me off guard. I guess I had expected them to be the same.

'11 335: 11427566327
'17 M2: 11427854445

Even more interesting is that the filter shows to be the same for the F80 M3 and the F82/F83 M4 as it is for the F87.

Checking my receipt from break-in service, this is the correct filter number. Just thought it was interesting.

No, the M235 uses the first part number I listed, from the E90.

Seems like the second one is M specific for some reason.

There’s a post on the forum about it. Visually they look the same. But no idea if any different. I went with the M part # as it’s only a few $ more expensive. Better to be safe than sorry... plus what if dealer sees that a non M oil filter was out in and you have engine concerns ?

I would guess that the M-specific part has its bypass valve set to a different pressure, potentially lower. Idea being that you'd rather contaminate the engine with some grit than completely oil-starve it...

It's a paper element filter not a canister type. BMW has never used a canister type as far as I know.

Bah, I forgot that the German stuff has the standalone paper thing that goes into the (usually plastic and easy to damage) canister. My TT and R32 both had the same... I blame mental overload from work.

Number of pleats the same? Maybe higher temperature glue in use?



I just find it very hard to believe they'd go to the trouble of making two different part numbers solely to overcharge ///M owners.

No worries, all my synapses firing together nowadays is becoming a rare treat.

Not sure if I like the newer system better or not? A decent amount of old oil is left sitting there in the housing when you pull out the used element. I usually just soak it up with a couple disposable blue shop rags. Plus you need to be careful not making a mess when getting rid of it. The older system was inverted 180 degrees with a metal outer canister and was a bit harder to deal with initially, but the residual old oil was collected in the canister and easier to dispose of.

Not sure the difference in design between part numbers here.

I do remember Toyota stating that their filters had something like 20% more pleats per volume than most other filters because of origami techniques.

No idea if the pleats are different. I guess there’s one way to test by weighing it. Someone want to send me a new filter ? :P. I have some super accurate scales.

That said the only notable difference I saw was that it’s made in Germany and has the ///M logo compared to a Mann OEM replacement
