Made it i have now the k&n filter installed on my cla. For the sound actually it sounds preaty much the same i would say just a little bit more engine sound, but the acceleration improved it feels more light weight it accelerates faster and with more power realy satisfiedwith that improvement. I will post some videos later

I have to imagine AMG's air filter is pretty efficient. Replacing high performance OEM air filters often yields little, if any, improvement to cooling. In fact, in a few instances, I've seen independent shops determine that certain aftermarket filters are actually LESS efficient than the OEM units. I'm not trying to dissuade anyone from doing this -- just advising you not to expect much of an improvement.

A few years ago, I was talking to the guy who owns the tuning shop that did some work on my Volvo. I did a bit of research on the springs I was having them install but still asked the owner whether he'd heard any complaints. His response was interesting. He kind of laughed and said something like, "I've been doing this so long that I've found, more often than not, anyone spending this much money on a mod tends to be happy with it." In other words, most people aren't objective about it -- they're just excited about the fact that they're modding their cars. We continued the discussion and he completely agreed that every mod is not a good mod. And, in fact, I knew at least one person who disliked the springs on his car (although we later learned that his car's suspension may have had a distinct set of problems). And, for what it's worthy, the springs were worth every penny. lol

I kind of look at air filters the same way. It's a cheap mod. Every one can afford do it. People who mod are happy to mod. Their "butt dyno" tells them that replacing a piece of paper between the outside world and the intake made their car faster and louder but, in reality, it's mostly (if not all) in their head. I've yet to come across any air filter that truly yields a different engine sound (it's always, "watch this video....aaaaand, there, did you hear that intake sound?...no? okay, go back and play it again...wait, aaaand...hold on, I missed it go back and play again...okay, listen closely....there it is...isn't that awesome? No, the OE version doesn't sound exactly the same!") and to the extent that the aftermarket filter is more efficient than the OEM unit, nobody's butt is feeling 0.3% increase in HP.

Replacing the whole intake system might improve performance slightly (provided the new intake doesn't actually pull in more hot air) but I wouldn't get my hopes up over a filter.

Thanks,
-Eric

I never liked the K&N because they use oil in the filter which can pass into your intake system and coat all your sensors which then eventually build up dirt. Usually will happen on the owners first cleaning and re-applying oil onto the filter. Make sure you do not over do it.

hi eric. I respect your opinion about any type of modification to a car. About the k&n air filters i have been chaging the oem filters of my cars to k&n ones, and maybe it´s just to subjective becouse i´m telling these but i have replaced my other 7 cars and to be honest i have realized that tha sound it doesn´t changes much as i posted the acceleration reaction does realy improves but the best of all the miles per galons are the ones that i have tested becouse i make my living of gasoline and diesel i own gas stations, i made that test with my 1991 chevrolet corvette with a full tank with oem filter i was geting 292 miles with a heavy foot, then i replaced it with a k&n filter and i started to get 323 miles with a full tank. Then i decided to change all my cars oem filters to k&n filters i also changed it to my 1/4 mille drag truck, pointles with that one becouse with a full tank it just gives 49 milles...... Or less hahahaha then i made an experiment becouse as you say the vehicles are made and designed with the oem type of filter the cardboard one so i bought 2 vacum cleaners original filters of carboard just the same as the oem filters of a car or suv or truck then i replaced one with a cotton fibber cloth. The fuction of a filter is to let air flow pass throu but to catch all the dirt and dust to geting to the engine the same as in the vacum cleaner or a vehicle i started using both vacum cleaners the first thing i noticed was that the card board filters get dirty quicker and wont let air flow pass, i replaced 2 oem card board filters by one washed and oiled to the cotton fibber cloth. At the end the vacum cleaner with the oem cardboard filters lasted me for a full year and the other vacum cleaner the one with the cotton fibber cloth lasted me a year and 4 months. That’s wy i decided to upgrade the air filters of my vehicles.

The only thing i learned about the k&n filters is what amg boost posted its very important not to soak in oil your k&n or you will have some problems with the maf sensor lived it with my 2008 focus st.

I agree with you eric the increase in power with a k&n replacement it wont be much. If any one wants to realy feel the change first of all yo will need to spend lots of money ecm reflash, biger turbo, exhaust system, down pipe, nos etc... Etc... And the list goes on.

I have been busy, outside of my home town. But i will make the video of the k&n replacement as soon as posible..

I Agree the part that people Like modding their car.

In some cases mostly older cars filters have got a good positive effect. In the modern cars I don't change the airfilters anymore. Mainly because there is no to little power gain.
The main reason for me at the moment to change the filter is to get a nicer sound from the Diesel engine :).

Thanks guys. And, that's a great point on new vs. old model efficiency. I was referring to newer models and should have been clearer. I also didn't mean to sound like I was putting down K&N or questioning the quality of their product. There may even be newer applications that yield performance, fuel efficiency or other improvements. I just wouldn't expect to see it on a newer AMG.

WOW, glad to see they have a filter, but your very correct Sue Esponte and AMG Boost..

Going with a full cold air kit or better filter can make a difference.. Look at Ea Filters, Dry but made of full synthetic media and good for 4 yrs or 100,000 miles with better airflow the wet gauze and oil.

Oil should be Just Synthetic and oil in the engine..

CLA model not listed yet but look at AMSOIL - Synthetic Oil, Motor and Engine Oil, Lubricants, Air Filters, Oil Filters and Greases to see the good stuff?
