Which Air Filters are best for a C43 AMG

[Gridlock]

How many more times are we going to have this debate? The only way your MAF will get mullered is if you over oil the K & N filters, which by the way does not need doing for 100,000 miles.

I've run K&Ns on mine for over 20K with no trouble, and yes if you're ruining your MAF then you're using too much oil. Golf too, and I've never had any problems with that running an oiled filter either - and the Golf is very sensitive to MAF issues, and has its fault codes read every week.

Seconded that it makes more induction noise too.

Although K&N give some great marketing spiel on their filters, I remain sceptical as to whether they offer better filtration than a pleated paper element.

Mercedes-Benz and AMG spent plenty on R&D when they build and design engines - I just don't see the standard pleated paper element being at all restrictive.

What type of filter elements do the M113 55 Kompressor engines run - pleated paper or oiled foam? I expect they flow signifcantly more air through the intake than a 4.3 N/A M113

I just can't see the benefit. Why not spend the extra cash on V-power or top quality tyres, something with real tangible benefit

All IMHO of course

To be really honest, I don't care about the filtration so much.... I like the noise !!!!

Why not remove the airbox altogether, or just stick a cone onto the intake. Works for thousands of the Saxo/Corsa brigade

 

[m2287]

Lol I think the only induction noise I would get from that would be the bang when my engine blew up !

Why not get one of those gadgets that plugs into the cigar lighter, and gives out the noise of a v8

I have used K&N's for years and had no trouble

I'm using K&N on my CLK500, not worried at all about MAF failures. The folks at K&N actually say something along the lines that nobody has ever come up with any evidence of MAF failure caused by their filters..

Will, 55 Kompressors use paper filters like you say. They are about 100 quid a pair from MB
So there would be no extra cash, as i could get a pair of ITG filters for 45 quid. Where as a pair of paper filters from MB are 85 quid

Because I already have it?! I just want more of it

Sounds like a funny gadget tho... Xmas prezzy for my mate who has just gone from an m3 to a diesel peugeot!

Dead right mate MAF sensors can deal with oil to a certain degree. Think of all the oil in a CDI intake system from a worn Turbo and they keep on going

From what I understand performance filters are only of a benefit if the paper element shows a pressure drop from one side to the other when the engine is requesting max power etc.

Yeah, now you are talking. I might get two of them :bannana::bannana:

Someone told me that some F1 teams use ITG air filters, and they are half the price of MB paper one's

No Brainer i think

If there is more induction noise then Happy Days

I run a Blitz cone filter on my RS Turbo, and the wastegate chatter i get is cool

I thought that was the BMC filters.
I believe Ferrari road cars have BMC filters as OEM, how true that is i,m not sure, but I did read it on here somewhere.

 

[Will]

Well to me, if Mercedes-Benz and AMG fit pleated paper elements into 5.4 litre, supercharged M113 V8 engines with circa 500bhp, I can't see what restriction they would have on a ~ 300bhp M113.

Surely the air filters don't need replacing every year? Most will last far beyond that, perhaps 4 years or more.

I am sure if cost is the issue, they could be sourced cheaper from an O.E manufacturer (Mann, Hengst or whoever) or with discount from a supplier like forum member 'Acid' who was offering 40% off service parts.

Surely something like a decat, viscous fan delete, head work or performance cams etc would be the way to more performance, not by putting in oily foam in the intake path

All IMHO of course

How is your C43/55 going Andy ? i am thinking of doing this conversion at some point. Are you still running the C43 Engine ECU ? how is the petrol consumption compared to the old engine, much different mate

The MB paper filters are fine, apart from being over priced because they have ///AMG written on them. Remember though MB are only going to spend the minimal amount of money on things like that, you would not see a Rallye or F1 car with a paper air filter in it ?

It depends on where you drive, but i would not leave a Air Filter un-changed for 4 years maybe 2 at the most.

I am doing other mods like de-cat, viscous fan delete aswell

Well to be honest I think the fuel consumption has gone up quite dramatically, though I,m not sure whether this is just my right foot
I am still running the 43 ECU and exhaust, though this will be changed as soon as the pocket will allow, I will be getting a De-cat and a Renn-Tec Airbox and re-map, though I must get a rolling road power run done before I do this.
To 60 there is no real significant difference but from there on it becomes more and more apparent that theres a 55 engine under the bonnet.
If you were to ask me is it worth it? not sure, what swayed it for me was the fact that I got the 55 engine cheap with 80k on it, and the fact that I was having issues with my Torque Convertor, it also needed new engine gearbox mounts and loads of other little jobs as well, if I had the engine changed all those bits could be dealt with upon reassembly.
Though I,m always sceptical on the C43 Gearbox weakness issue as afterall it is only a variant on 722.6 box, and as I was getting the Torque Convertor reconned I thought I would get the gearbox re-built before it blew and self-destructed to such a degree that it could,nt be rebuilt.
At over 150k miles no faults were found other than a hairline crack in the Electro plate, which was replaced, and just general wear and tear for a 150k Gearbox.
