BMW performance intake filter element replacement

[NorCalZman]

I see that BMW has discontinued the filter replacements for the performance intake. Napa Gold 6301 was identified as a good replacement but Im not finding that online either and they dont seem to have a “superseded by’ or other cross reference on the Napa website.

Does not appear anyone has found a good replacement in the last few years and shared it on the forums (all the threads Im finding are from 2015 or earlier).

Any other Performance Intake owners here? Found a new replacement filter recently?

I also wouldn’t mind knowing what is a good filter to use, mine probably needs replacing

I bought the NAPA filter at their store several years ago but haven't installed the intake yet! Wish I'd purchase more than one.

I replaced mine late last year, used the Fram CA7598 and it fit perfectly

Thanks guys. That cross reference site is genius and looks like the Fram filter is on the list too.

How often do you guys change your filter?

WIX 46301 Discontinued
MAHLE LX2931 If we want to keep things German, this is an option. BUT Im having trouble finding it online.

I might suggest you guys buy a few filters of your choice as these seem to be mainly for OLD GM cars and they are being discontinued.

In my boredom while drinking my tea this morning I did some digging on testing and found an interesting YouTube video about engine air filters, in which he tested Fram, WIX, K&N, Purloator, and a few others.

Long story short, despite having some of the least filter pleats, the WIX filtered out particles the best while also showing some of the best 0-60 times in the test vehicle.

I think I am going to buy a few WIX 46301 filters for storage. Edit: Looks like WIX has stopped making the 46301 filter but there were a few new old stock on amazon so I bought them. Napa sells something under the Proformer name under part 26301 that has similar dimensions so I’ll order that and compare it to the WIX filters I found online and report back. Though, it is a lot cheaper than the WIX was so Im going to guess the quality is not as good.

I'm using a Mahle LX2931 and it fits pretty well, not perfect, but it definitely seals.

Where do you buy it? I am unable to find it in stock.
