Just unbuckle the two latches and lift the cover up and roll it over to access the filter element. There are three slots on the back that accept three plastic square alignment tabs before you snap the cover back in place. There is no need to remove the air duct (looks like a hose).

I have seen a photograph of a 2009 300C Heritage Edition and it is spectacular! One thing different: The Chrysler wing on the trunk looks wider and it has the red, white and blue Heritage Edition badge in the center of it. They also have LED turn indicators on the mirrors and puddle lamps. The rear spoiler is molded into the trunk lid and the rear deck brake light is relocated to the trunk as well (like the 300M). The dual exhaust stainless steel tips are rolled on the edges instead of just cut off. The interior is improved as well with more wood and chrome trim. The MyGig entertainment center is a great feature also. The Navigation system is now touch screen operated, much better than my 2006 model the requires everything done with a twist button selector, and a graphic keyboard and enter button. Too much trouble! Chrysler is listening to everyones' suggestions and making changes to improve. The prices have not gone up much since 2006 either. The cars are just getting better.

Thanks for the info on the air cleaner filter. I could'nt think of the proper name for the air duct. Thanks again!

You are welcome. There is one other thing I failed to mention concerning the air filter on the 300C as well as a lot of other late model cars with high performance engines. I have been using K & N high-flow, permanent, washable air filters on all my cars for a number of years. About every three months, rather than change the filter, I clean it in my kitchen sink with a special detergent and re-oil the filter element when it is dry and put it back in the intake plenum. The idea of a high-volume, low restriction air filter is better performance, mileage and economy because you don't have to buy another air filter for about 100,000 miles. Well, that is what i got out of them with my older carbureted engines. However, on all my fuel injected engines with the modern electronic controls on everything, I am not seeing the same results. My mileage has not changed, and the performance is about the same as well. I questioned others about the reason why, and the best explanation was as follows: Most modern engines have a "mass air flow sensor" in the intake manifold that precisely measures the CFM of combustion air that is drawn into the combustion chambers and adjusts the amount of fuel released by the injectors to maintain the exact ratio of air to fuel mixture consumed by the engine. It doesn't matter if your air filter is covered in dirt and restricting 50% of the air or if it completely removed and the maximum amount of air is allowed into the engine. The computer will always keep the same fuel to air ratio, so it will cut back fuel to match an excess of air. The horsepower will vary with the amount of fuel allowed to feed the engine cylinders as in any car, but the mass air flow sensor will limit any benefit of high volume intake air automatically. The carbureted engines will take as much air and fuel as you can cram into them, even if your use a blower to do it. But, modern engines are built with high performance, reliability and fuel economy in mind. Switching to a re-useable, oiled, low restriction filter doesn't really gain anything. In fact, on some vehicles, they are expressly forbidden because they allow larger particles to pass through the filter and can void your warranty. I am going to remove my K & N filters and go back to paper element disposable filters. they don't cost much and are available everywhere. I thought you might find this information useful, in case you were considering changing over to a permanent filter.

You are correct - and in some cases, the K & N will blow up a mass air flow sensor. Some companies will stand up to replace it under warranty, but some will void your warranty if they see a K & N in there. How do I know? Had one on an Infiniti I owned, the mass air flow sensor failed as a result. Nissan stepped up and fixed it for me, but warned me they would not do it again if I continued to run the K & N in there. They are an outmoded aftermarket technology now.

I think the majority of problems people have with K&N type filters is over-oiling. Oil then coats the little MAF sensor and that's not good. A throttle body cleaner can remove the film but if it's oiled correctly in the first place it will never happen.
I have a drop-in K&N in my wife's PT Cruiser turbo and it works well. I used a cone K&N filter in my old Mysitque for nearly 10 years and no problems after I learned not to put too much oil on it. 
I have dual K&N cone filters on my Viper that seem to work fairly well.

The President-Elect's car

I read where the President-Elect had to give up his Chrysler 300C in favor of a hybrid SUV due to pressure from the environmentalists. Does anyone know what color and model 300 he had? Thanks

Sunroof Drain Blocked

Now have 40K on my 300C and no major issues! However, it has been raining a lot recently and water started dripping down the back grab handles and the passenger side seat belt holder. When you open the sunroof, you'll see two drain holes - one in each front corner (hard to see, but they are there). These holes drain down through the door frame (between the front door and the fender) - you can see the drain tubes by opening the front doors and looking for the small 1/4" tube that sticks out about 1 1/2" long about half way down the door frame. (Becareful not to move the door and trap your fingers as you look!) The problem is that the insulation in the front fenders can move and block the drain tube that empties out between the front door and the fender. I found my problem by trying to blow a blast of air through the drain hole and it must have dislodged the blocking insulation and I saw water dripping out. I checked the other side of the car and pushed the insulation slightly towards the fender and water came pouring out. Hence - check this insulation if you are having this problem.

I have used K & N filters for all my vehicles and NEVER had a problem with them period. Carbs or Injected, every one performed flawlessly and every one did increase horsepower and mileage. I have recommended these for years to anyone who will listen and THEY have had flawless performance. My latest is a 2008 Honda Ridgeline, 15.5 mpg to 19.9 in town, (63 Impala 383 Demon Carb, 2000 Mercury Sable injected, 2003 GMC Sonoma injected, 2008 American Iron Horse carb. also have them)
I agree that the cleaning may be an issue as folks are cleaning them way :too often. Once every 6 months, "clean and dry it completely, oil it lightly" then put it in. The thing will last 1,000,000 miles. My friend Dock just put one in his 300 and it's doing great...better mileage and more power.
Thanks for the opportunity to share info and experience. My personal experience with Nissan is .....Well (I am not allowed to use bad language) not very good. My Nissan Maxima SE 2001 (traded for the Honda) was a sensor/EGR valve eater with paper elements or K&N, premium fuel an all.

It must have been yellow! If all it takes is a bunch of whiners to make him change vehicles, who else is going to manipulate him? He has to be the first president to let a group of fanatics dictate what he should drive. Last time I checked, most presidents get driven around in a limo with lots of secret service protection anyway. Are those same "environmentalist" also concerned with the MPG rating of Air force One? The little photo-op in NYC was reported to cost about $200,000.00.
