Not quite sure what you are saying here.

These forums deal with the DC's 2005 Chrysler 300 series. The "C" model has the filter builtin. I don't know which others have it or not. But If they do not, it may be possible to get the parts from Mopar and install it. Shouldn't require much work; it doesn't even look as if sheet metal is involved, just some plastic or something like that. I would go to a dealer's lot, and compare the area under the hood between the right windshield wiper pivot and the right fender up by the firewall.

But on an '05 Benz? Is that what you really mean? If so, you are in the wrong pew in the right church. You need to go to mercedes.com or so. :^))

mileshoover.........your post brought a question to mind. Can we change our A/C filter? I run my A/C all of the time, and I think the A/C is starting to smell funny.

Sure, but I would go to the dealer first and get the Mopar replacement filter in hand. I know the maintenance manual gives a recommended time to change these filters, but logically if things smell, your filter may need to be replaced sooner. It is on the regular maintenance schedule, also., but don't recall exactly.

One you have the filter in hand, just go under the hood on the right side up by the firewall. You will see a ventillated door in the horizontal air grille at the firewall just between the right wiper pivot and the right fender. Open that door carefully, pull out the filter and replace it.

When picking up the replacement filter, ask the parts guy if the filter can be installed "as is" or if it needs to be sprayed with something.

Perhaps one of our Service Manual owner members can enlighten us on this point.

I have had mine out (nosey), but have not seen a need to replace it yet. Whatever you do, do NOT remove the filter and then drive the car for any period of time. Doing so will be just like running a home AC unit without a filter -- you will contaminate the ducts without them being filtered.

Now that may seem like trivia to some, but if you or yours suffer from allergies, you will know exactly what I mean.

Thanks mileshoover. You are a blessing to this forum. I do have allergies, and was really happy to see that the 300c had an A/C filter. I will let you know how it goes after the filter is replaced.

Just so you are aware, the 300C only has the filter from the factory if you have the Protection Group.

Miles, the only thing that the manual stated is that be aware of the arrow to indicate air flow direction and the "rear of vehicle" label on it. Said nothing about spraying something.

OK guys, sorry for being too terse...but by "MB" I meant "Midnight Blue" in my '05 C ! And, no, I don't have Protection Group II, so I suppose that means there's a big gaping hole under the right front cowl where the $15 filter goes. Only prob is, the dealer couldn't locate a part number for the filter. Too new for aftermarket?

More wisdom from MagnumFreak on DodgeMagnum.net:
The filter part number: 04596501AB
Also, if you don't have Protection Group II, you will need to purchase the housing for the filter--a (plastic?) screw-mounted bracket for the filter to sit securely inside.

Could not find a part number on the filter housing. I did look at the installation and if you are comfortable with basic tools installing it shouldn't be that difficult. You would need to order the "particulate air filter housing" (that is the name from the service manual), not sure what the cost is. You would also need to remove your windshield wipers. Not as difficult as it sounds. There is a small plastic cover near the bottom of the wiper blades. Romove the cover and the nut underneath. Wipers should just slide off. Then remove the plastic cover that runs the length of the windshield. There appears to be 6 screws around the permiter of the cover. The filter housing installs with two or three screws.

I am sure the parts counter person can give you a detailed blow up drawing of the filter housing.

Thanks Indy. I haven't been out to look yet, but are those real screws holding down the cowl or are they those plastic half-turn "rivets" that pop no matter how careful you are (or aren't...)? Think I'm better off going to the nearby Dodge parts desk than Chrysler?

Good questions. I have read of some people permanently removing the cowl, and I'm sure many have taken it off just to stare at/gloat over their Hemi engine, only to put it back on. I haven't heard anyone complain yet here or on DodgeMagnum.net about problems with putting the cowl back on after having taken it off.

As far as Dodge desk versus Chrysler, I had always assumed that DC parts were parts, ordered from the same warehouse in car-Shangri-La... but seriously, I'd work with whatever local DC dealer parts department you have the best rapport with.

In my limited experience, I get the best results when I'm not dealing with angry Luddites in charge of ordering parts from the often-complex computerized inventory systems used nowadays.

if you can find the filter housing , you can just remove 2-10 mm nuts that hold the plain housing to the 300's body and replace with the filter housing unit . Not sure if the dealer will sell you just the filter housing , its just a piece of plastic with a flap on top that the filter slides into . the plastic screw on the cowl are just twist off , ,if you look close you will see a small arrow on the screw top .This should point towards the window to hold the cowl unit in place

I sure would like to add the cabin filter and housing to my 300C. Lots of RED dirt on Maui! Please post the housing part numbers for all the housing pieces you had to order. TIA!

Plenum Part #

The plenum assembly is part # 4806294AA. It includes the complete plenum (big bucket-type piece), the filter housing and the filter.

Not sure what is necessary to install it. Anybody done it??

Earlier I installed the cabin filter element -- just jammed it up against the screen on the firewall. Fits very well on the left, top and bottom -- the right side is deformed a bit. Added 2 pieces of duct tape just to be sure it wouldn't flop around in the plenum. Works fine.
