Problem with afe filter and possible solution.
I just installed my afe oiled filter:
http://www.m3post.com/forums/showthread.php?t=195970 The problem with the filter is that the whole side where the tension knob pushes into the filter is soft (compared to the hard plastic on the oem filter). This seems to create a loose connection under pressure. Many have noticed rattling etc. Someone on this forum noted how easily the filter peels away from the intake manifold side. This is not true of the oem filter. To rectify this problem, I cut out part of the oem filter plastic and placed it between the spring and the afe filter. This also creates a larger surface area under tension from the spring. Part where the filter easily peels off.... OEM Piece cut out.... Installed in car: Does the intake cover go OVER the rubber tube? Can anyone check for me please??? I left it like this for now. Closed it up, took it for a drive and it is as quiet as a mouse (except for the sucking sound) |

Nice fix! Thanks for posting.
I used some rubber silicone and it holding quite well, it also very easy to remove if need be.

Great post and thanks for the pics. I just got my aFe filter but haven't installed it yet. Perhaps I'll try your method.

FWIW, the orange Active Autowerke filter has a milled aluminum endpiece set into a hard plastic endcap for just this purpose. Although it's got a paper element is has many more folds than stock or the AFE filter, not sure if this is better or worse for performance.

Dumb question here, but does the dry AFE filter fit tight and snug as OEM and the oiled filter fit loose? Is there a difference in design/fit? I read on the web sight and other posts that the oiled filter has a slightly higher air flow. sounds like I'd go with the dry element and not have to worry about doing my own mod to get the oiled to fit properly. Is this the case??? |

You can see the filter has a soft ends with a hard nylon-like internal grid frame and cap, you can also see the Made in Austria label but the rest of the manufacturers info redacted, . The AA filter must come from the OEM supplier based on the lettering on both and the similar frame. See the EU vs US and then the part number on each piece. |

Hmm... thanks for posting the pics. Looks like the AA filter may just be a stock EU filter with a different cap. I think there were posts about the spring loaded knob being a different length for non-NA cars in the early AFE treads. So, a cap change may have been required to fit. |

Notice that the aluminum cap goes thru the frame and visible at the interior of the filter, not a simple modification for a $54 filter, I'm guessing it came this way from the OEM manf. to someone's spec (AA) if it's not an off-the-shelf EU OEM part. Compared to the US OEM part this filter has at least twice the number of pleats. |
