Air filter housing; Question from earlier post

Recommended Posts

I'm planning to replace the air filter and have reviewed earlier posts with pics on the procedure. From what I can tell, I will disconnect several sensor wires and move the oil filler pipe, but i'm still confused on how the housing with the 3.8 logo is attached / lifts out.

The bolts on my 996 aire filter housing were more straight forward

Any hints/clarification?

Just did this on my '05. Some important tips below:

There is NO bolt. Once you remove end of large air intake hose, you pull the entire air clearer house UP, with a BIG tug, and the entire unit pulls out. Also, the 7 screws holding the two-part housing together are NOT phillips head, but look like a torx (???). I happened to have the right size of flat head screwdriver that fit into the torx opening so I could screw in/out. I was lucky I had something that fit.

Filter itself goes in easily, but be sure it is SEATED. I used a blunt flat head screwdriver to press filter edge into housing - ENTIRELY around the OUTSIDE edge. Just setting it in the housing did NOT seat it.

I also spent about 10 minutes cleaning the outside of the housing. While doing this, I cleaned what appeared to be stretched SILK on one end of the underside of housing. I used a VERY SOFT detail brush to do this and a good deal of grit-like debris came off.

I did this at 5,500 miles. Not much dust in filter from the looks of it, but when I banged the used filter in the sunlight, a lot of dust came out.

the entire process took me about 45 minutes, but that includes a lot of time sorting the process out and the cleaning. If I did it for a lving, I could probably do it in 10 minutes.

Hope this helps

yep, that does help. much appreciated

I just removed the air cleaner assembly and it is as all of you have described. It's pretty much just sitting in there. This is definitely different than my 996.

Unplug the 2 sensor connectors as described above, and unplug a u-shaped vacuum line from one of those sensors. What wasn't mentioned is that there 2 cable clamps, one the right side and one attached to the back of the snorkle-like air intake that gets the air from the spolier grill. A simple twist does it on both. Move the oil filler tube out of the way and you're ready to lift out

Lift straight up; there's a gromment in the front that sits on a post as a friction-type fit. Pull up.

Thanks guys!

The purpose was to fit a BMC filter and cold air kit. :)

Here is the over-priced but seemingly effective cold air kit. my butt-o-meter tells me there is at least another 25-50hp now (tongue-in-cheek wink). no affiliation, yada, yada


and the infamous flapper valve which opens/closes to mitigate loud intake sound (now present with the kit)


plug and cover
