K&N filters for 55AMG. Pros and cons?
PROS:

More speed w/filter.

CONS:

1. MB WARRANTY issues;

2. Fast enough as is (faster than the C5 Corvette);

3. Time-consuming/messy to oil the filter regularly;

4. Particle contamination & damage to AMG engine, if not properly maintained/installed;

5. Fuel/Air/computer setting problems;

6. Not in concert w/ MB specs - add'l. comlications; and

7. More unforeseen cons: Stalling, hesitation, rough idling, etc.

Summary:

Vivo try it, you might like it.

I won't use it.

Some of those CONs aren't correct.

1. MB WARRANTY issues
7. More unforeseen cons: Stalling, hesitation, rough idling, etc
5. Fuel/Air/computer setting problems;
3. Time-consuming/messy to oil the filter regularly;
Every 30,000 miles

If 2. 4. and 6. are correct, then 1. must be correct as well. Also some of the remaining points may have varying degrees of relevance

1. MB WARRANTY issues;

2. Fast enough as is (faster than the C5 Corvette -

Corvette 0-60 mph = 5.2 seconds //

CLK55 AMG 0-60 mph = 4.9 sec.!!);


3. Time-consuming/messy to oil the filter regularly;

4. Particle contamination & damage to AMG engine, if not properly
maintained/installed;


5. Fuel/Air/computer setting problems;

6. Not in concert w/ MB specs - add'l. complications;

7. More unforeseen cons: i.e. stalling, hesitation, rough idling, etc.; and

8. If problems arise, you are entering a LEGAL MINEFIELD.

I'm sorry, I just chose not to respond to those. I don't think in the history of K&N filters have they ever voided any warranty. In order for anything to void your warranty it has to be shown as the direct cause of the problems. While K&N filters tend to let more particles in, they would not be noticed in the 100,000 mile (max) warranty for MB. If K&N filters could void your warranty, then so could choosing Shell over Chevron. And in the rare instance that both hell freezes over and monkeys fly out of my butt, you could always just put your stock filters back in before you go to the shop.

Per the Magnusson Moss act, any vehicle manuf. would have to prove a problem was caused by the specific part in question to void warranty work. The burden of proff is on the Manuf. and most times, manuf. won't screw people around over this (unless it's a clear cut warranty void problem due to after market accessories) as it costs them more to fight it in court.

Maybe Moderator Drew, Esq. could provde more insight into this specific act.

Vivo is looking for a recommendation.

It's obvious, that I do NOT recommend the K&N air filters.

What is is your recommendation & why?

I think from the nature of most of my posts that I recommend many modifications to the CLK, the most basic being filters/exhaust. While I like K&N filters, I've heard that ITG filters are even better. I currently have a stock intake with the stock filters. However, I'll soon be switching to either an Evosport Intake or Kleeman Supercharger. While the supercharger would likely be to blame for any engine problems, it would still need to be proven as the cause.

awiner is generally correct on the law, but you must bear in mind there are legal burdens, and then there are practical burdens. While a manufacturer does have the legal burden to show a mod caused the problem in question, many mfgrs/dealers avoid ever dealing with this issue by placing the burden on the owners to investigate their rights and to sue them. In other words, many mfgrs (and the dealers who help administer the mfgr's warranty) may say a mod "voided" your warranty or is responsible for your problem, and while this may be complete BS from a factual or legal standpoint, it places the burden on the owner to get a lawyer and sue them (or at least threaten them, at which point many of them capitulate). Of course, many owners don't know about the law and simply take what the mfgr/dealer says at face value and pay up. And even as to those owners who know their rights or find them out, most people aren't going to pay a lawyer as much or more than the amount in issue (MM does have a provision providing for the recovery of attny fees by a successful plaintiff, but finding a lawyer to take such a case with that as the only possible source of his fee is not easy).

My CLK55 is my first Mercedes so I don't know how MBUSA approaches these issues, but I can't imagine a K&N would cause any serious problem, and MB would have to be the worst of the worst to take a hard-line position on that one with respect to an engine failure or something.
