Air Filter Solution for Pre 09/09 M3s

[anotherchengman]

As some of you have heard, BMW/Mahle have discontinued the charcoal lined (p/n 13727838805) air filters for pre 09/09 M3s. The difference is the spring loaded nub in the intake housing. I have designed a ABS printed replacement to allow you to reuse your existing housing with the later paper filter (p/n 13727838804).

If anyone is interested, I would be happy to make and sell these to support those who do not want to replace their air boxes or run aftermarket filters.

Hi, this shocked me a little bit. I have 2008. But per my research this applies "only" to US models, right? For EU models (mine) I use the 13727838804, right?

It really sucks, sorry about that my US friends.

Yes it applies to US models only it seems. The filter had an activated carbon layer for evaporative gases when engine is off.

Thanks for that. Your solution is good. I saw it on some other websites also when doing the research. I hope that the ABS is able to go through heat cycles without shrinking or changing its shape. Btw you could also publish your STL file, I guess people from the forum would appreciate it Still many people would buy it because they don't have a printer.

Just an FYI, you can still search for Mahle LX1667. They are the same filters that came from BMW and are still available.

The mahle is discontinued too. Whatever is being sold is the remaining stock
