What kind of air filter is best choice for 500E

Air filters are very important on every car.
I had K&N filters and I replaced them with MB original air filters which you can never go wrong.
K&N filters may effect the platinum wires of the MAF sensor or throw some codes off, but I may be wrong. Dirty air filters has been one of my pet peeves since I was 16 years old. I just hate dirty air filters.

Any of these air filters listed will be fine to use:
K&N filters are really not worth the hassle.
The biggest issue with them that I see, is that often, owners don't know how to properly oil them, and they are then over-oiled. This can negatively affect the MAF hot-wire on the E500E.
I have never (at least in E500E applications) seen any hard statistic that shows that K&N filters add any torque or horsepower to the car. Just go with the Mann or Hengst filters, or the factory MB filters, and change them every 15,000-20,000 files. I have usually done mine every 20K over the years.

Spot on. If the K&N filters are oiled properly and the oiling instructions are followed, you won't have an issue with the MAF. I have run these in most all of my cars for many years without issue.
Whenever i used k&n it felt like hearing some rumble or hiss when flooring .. idk maybe just my imagination for paying that much for that k&n ? Lol
But as gsxr mentioned there is zero power gain .
And if u don't know how to properly oil them , please save yourself the money and trouble. Maf sensors cost alot...

I know that maf costs a lot, thats why i ordered paper filters what i found from 500eWiki.
If you really insist on using k&n , thats fine you can just buy it and every maintenance just buy a new pair xD then u will have also no problems because they are already pre oiled in the box..
Just regularly change the filters , do no let it become brittle .

+1 w/ Joe, I've never had a problem w/ K&N. If you read the directions for cleaning it just takes a little re-spray of oil after cleaning. People who have messed up their MAF have just way OVER-OILED the filter.
Don't blame K&N for that problem. Chalk it up to stupidity
What is the real-world benefit of using K&N air filters? There have been plenty of people over the years who have said there is zero difference in power. I "grok" the 'reusability' factor, but there are complications with that ... namely having to remove and re-oil the filters periodicially, danger of over-oiling them, initial cost, and so forth.
Seems much easier (given that there seems to be no real world power benefit) to just use disposable filters and be done with it.
Or is it a psychological thing that K&N are "race grade" filters and thus contribute to a "high performance" racing image for one's engine?
I could totally see it if dyno tests showed that K&N filters provided 10 more HP or something....
What am I missing?

I know for sure that some other brands as bmw m3 e46 e39 m5 uses them for hp increase , HOWEVER , the engines i have seen runnin on dyno they were all modded engines . Carbon airbox, some camshaft or bored heads .
And therefore this still is an issue of over oiling.
There maf sensors are so sensitive that the oil will burn in on the film and cook up the sensors.other than that they had plenty of room to chip or upgrade their engines and thus uses k&n or green filters to let the airflow increase . May be a lower end increase as most of them start boosting at 4 k rpm . Especially the m3 . Even the smg II with launch control revs up to 4k before "launching" to give its maximum power.
This is not the case for our 119s .as for the m120 v12 . BT and DT.
Mostly of the guys who are using this have a complete different setup as their engines are modified completely.
Correct me if i am wrong guys .
Saw hp increase on these engines.
But i repeat , these were modified engines who already had hp increase. The reason was to take every bit of extras on the engine.
I aint cont k&n . But its like gerry said ..
Just my 2 cents on this people .
Edit : i am on a restoration project right now for my 500e
If i would ask this question to my self , well , If i would use k&n or green , i aint gonna oil it up everytime. Just replace with new ones every maintenance. This will only give me the feeling like new filters of k&n .
My bet is on the green hornet filters, reason is because they look green , i would see dirt more easily than the red one . As when oiled and used several times they start go dark. Even with green i will always put new ones .
No offense guys but i find it a little bit of too risky to reoil a filter on a engine that is already rare on our cars , i would ( as everyone else would ) to have a good engine and keep them good and healthy , why risking so much effort and money for a reason that does not exist for my engine ?
Thats just my tought. I could be wrong guys lol . Dont shoot me xD

No argument here, "To each his own".
I installed them when I first bought my car with 89K miles on it. At that time they were the "Cat's Meow" or whatever. They are still in the car at 142K and are going to stay. I've cleaned and oiled them twice. I see no real advantage now (maybe a little more aggressive induction sound) but I spent the money and I'm sticking with them.
K&N gurantees them for a million miles, so unless upon inspection the look bad or something they stay.
lol
Bought mine with K&N filters in it... no change. Bought my E46M with K&N in it... no change. Bought my W220 S55 and Audi Allroad 4.2 with factory filters... no change. “Therefore remain as you were first called”...
I see no reason to change to OR from K&N filters, quite frankly, and no one has been able to convince me either way over the years. On the E46M, there is definitely a difference in induction sound, but there the K&N is an open cone. Here, it sits in the air box so the induction sound is probably the same.
Thinking of it, I should change on one of these cars just to see for myself if it’s worth it. Nah...
maw
